Chapter 13. Storage Engines

MySQL supports several storage engines that act as handlers for different table types. MySQL storage engines include both those that handle transaction-safe tables and those that handle nontransaction-safe tables.

MySQL Server uses a pluggable storage engine architecture that enables storage engines to be loaded into and unloaded from a running MySQL server.

To determine which storage engines your server supports by using the statement. The value in the column indicates whether an engine can be used. A value of , , or indicates that an engine is available, not available, or available and currently set as the default storage engine.

mysql> *************************** 1. row *************************** Engine: FEDERATED Support: NO Comment: Federated MySQL storage engine Transactions: NULL XA: NULL Savepoints: NULL *************************** 2. row *************************** Engine: MRG_MYISAM Support: YES Comment: Collection of identical MyISAM tables Transactions: NO XA: NO Savepoints: NO *************************** 3. row *************************** Engine: MyISAM Support: DEFAULT Comment: Default engine as of MySQL 3.23 with great performance Transactions: NO XA: NO Savepoints: NO ...

This chapter describes each of the MySQL storage engines except for , which is covered in MySQL Cluster NDB 6.X/7.X. It also contains a description of the pluggable storage engine architecture (see Section 13.4, “Overview of MySQL Storage Engine Architecture”).

For information about storage engine support offered in commercial MySQL Server binaries, see MySQL Enterprise Server 5.1, on the MySQL Web site. The storage engines available might depend on which edition of Enterprise Server you are using.

For answers to some commonly asked questions about MySQL storage engines, see Section B.2, “MySQL 5.5 FAQ: Storage Engines”.

MySQL 5.5 supported storage engines

: A transaction-safe (ACID compliant) storage engine for MySQL that has commit, rollback, and crash-recovery capabilities to protect user data. row-level locking (without escalation to coarser granularity locks) and Oracle-style consistent nonlocking reads increase multi-user concurrency and performance. stores user data in clustered indexes to reduce I/O for common queries based on primary keys. To maintain data integrity, also supports referential-integrity constraints. is the default storage engine as of MySQL 5.5.5.
: The MySQL storage engine that is used the most in Web, data warehousing, and other application environments. is supported in all MySQL configurations, and is the default storage engine prior to MySQL 5.5.5.
: Stores all data in RAM for extremely fast access in environments that require quick lookups of reference and other like data. This engine was formerly known as the engine.
: Enables a MySQL DBA or developer to logically group a series of identical tables and reference them as one object. Good for VLDB environments such as data warehousing.
: Provides the perfect solution for storing and retrieving large amounts of seldom-referenced historical, archived, or security audit information.
: Offers the ability to link separate MySQL servers to create one logical database from many physical servers. Very good for distributed or data mart environments.
: The CSV storage engine stores data in text files using comma-separated values format. You can use the CSV engine to easily exchange data between other software and applications that can import and export in CSV format.
: The Blackhole storage engine accepts but does not store data and retrievals always return an empty set. The functionality can be used in distributed database design where data is automatically replicated, but not stored locally.
: The Example storage engine is “stub” engine that does nothing. You can create tables with this engine, but no data can be stored in them or retrieved from them. The purpose of this engine is to serve as an example in the MySQL source code that illustrates how to begin writing new storage engines. As such, it is primarily of interest to developers.

It is important to remember that you are not restricted to using the same storage engine for an entire server or schema: you can use a different storage engine for each table in your schema.

Choosing a Storage Engine

The various storage engines provided with MySQL are designed with different use cases in mind. To use the pluggable storage architecture effectively, it is good to have an idea of the advantages and disadvantages of the various storage engines. The following table provides an overview of some storage engines provided with MySQL:

13.1. Comparing Transaction and Nontransaction Engines

Transaction-safe tables (TSTs) have several advantages over nontransaction-safe tables (NTSTs):

They are safer. Even if MySQL crashes or you get hardware problems, you can get your data back, either by automatic recovery or from a backup plus the transaction log.
You can combine many statements and accept them all at the same time with the statement (if autocommit is disabled).
You can execute to ignore your changes (if autocommit is disabled).
If an update fails, all of your changes are reverted. (With nontransaction-safe tables, all changes that have taken place are permanent.)
Transaction-safe storage engines can provide better concurrency for tables that get many updates concurrently with reads.

You can combine transaction-safe and nontransaction-safe tables in the same statements to get the best of both worlds. However, although MySQL supports several transaction-safe storage engines, for best results, you should not mix different storage engines within a transaction with autocommit disabled. For example, if you do this, changes to nontransaction-safe tables still are committed immediately and cannot be rolled back. For information about this and other problems that can occur in transactions that use mixed storage engines, see Section 12.3.1, “, , and Syntax”.

Nontransaction-safe tables have several advantages of their own, all of which occur because there is no transaction overhead:

Much faster
Lower disk space requirements
Less memory required to perform updates

13.2. Other Storage Engines

Other storage engines may be available from third parties and community members that have used the Custom Storage Engine interface.

You can find more information on the list of third party storage engines on the MySQL Forge Storage Engines page.

Third party engines are not supported by MySQL. For further information, documentation, installation guides, bug reporting or for any help or assistance with these engines, please contact the developer of the engine directly.

Third party engines that are known to be available include the following; please see the MySQL Forge links provided for more information:

PrimeBase XT (PBXT): PBXT has been designed for modern, web-based, high concurrency environments.
RitmarkFS: RitmarkFS enables you to access and manipulate the file system using SQL queries. RitmarkFS also supports file system replication and directory change tracking.
Distributed Data Engine: The Distributed Data Engine is an Open Source project that is dedicated to provide a Storage Engine for distributed data according to workload statistics.
mdbtools: A pluggable storage engine that enables read-only access to Microsoft Access database files.
solidDB for MySQL: solidDB Storage Engine for MySQL is an open source, transactional storage engine for MySQL Server. It is designed for mission-critical implementations that require a robust, transactional database. solidDB Storage Engine for MySQL is a multi-threaded storage engine that supports full ACID compliance with all expected transaction isolation levels, row-level locking, and Multi-Version Concurrency Control (MVCC) with nonblocking reads and writes.
BLOB Streaming Engine (MyBS): The Scalable BLOB Streaming infrastructure for MySQL will transform MySQL into a scalable media server capable of streaming pictures, films, MP3 files and other binary and text objects (BLOBs) directly in and out of the database.

For more information on developing a customer storage engine that can be used with the Pluggable Storage Engine Architecture, see Writing a Custom Storage Engine on MySQL Forge.

13.3. Setting the Storage Engine

When you create a new table, you can specify which storage engine to use by adding an table option to the statement:

CREATE TABLE t (i INT) ENGINE = INNODB;

If you omit the option, the default storage engine is used. The default engine is as of MySQL 5.5.5 ( before 5.5.5). You can specify the default engine by using the server startup option, or by setting the option in the configuration file.

You can set the default storage engine to be used during the current session by setting the variable:

SET storage_engine=MYISAM;

When MySQL is installed on Windows using the MySQL Configuration Wizard, the or storage engine can be selected as the default. See Section 2.3.4.5, “The Database Usage Dialog”.

To convert a table from one storage engine to another, use an statement that indicates the new engine:

ALTER TABLE t ENGINE = MYISAM;

See Section 12.1.14, “ Syntax”, and Section 12.1.6, “ Syntax”.

If you try to use a storage engine that is not compiled in or that is compiled in but deactivated, MySQL instead creates a table using the default storage engine. This behavior is convenient when you want to copy tables between MySQL servers that support different storage engines. (For example, in a replication setup, perhaps your master server supports transactional storage engines for increased safety, but the slave servers use only nontransactional storage engines for greater speed.)

This automatic substitution of the default storage engine for unavailable engines can be confusing for new MySQL users. A warning is generated whenever a storage engine is automatically changed. To prevent this from happening if the desired engine is unavailable, enable the SQL mode. In this case, an error occurs instead of a warning and the table is not created or altered if the desired engine is unavailable. See Section 5.1.7, “Server SQL Modes”.

For new tables, MySQL always creates an file to hold the table and column definitions. The table's index and data may be stored in one or more other files, depending on the storage engine. The server creates the file above the storage engine level. Individual storage engines create any additional files required for the tables that they manage. If a table name contains special characters, the names for the table files contain encoded versions of those characters as described in Section 8.2.3, “Mapping of Identifiers to File Names”.

A database may contain tables of different types. That is, tables need not all be created with the same storage engine.

13.4. Overview of MySQL Storage Engine Architecture

The MySQL pluggable storage engine architecture enables a database professional to select a specialized storage engine for a particular application need while being completely shielded from the need to manage any specific application coding requirements. The MySQL server architecture isolates the application programmer and DBA from all of the low-level implementation details at the storage level, providing a consistent and easy application model and API. Thus, although there are different capabilities across different storage engines, the application is shielded from these differences.

The MySQL pluggable storage engine architecture is shown in Figure 13.1, “MySQL Architecture with Pluggable Storage Engines”.

Figure 13.1. MySQL Architecture with Pluggable Storage Engines

The pluggable storage engine architecture provides a standard set of management and support services that are common among all underlying storage engines. The storage engines themselves are the components of the database server that actually perform actions on the underlying data that is maintained at the physical server level.

This efficient and modular architecture provides huge benefits for those wishing to specifically target a particular application need—such as data warehousing, transaction processing, or high availability situations—while enjoying the advantage of utilizing a set of interfaces and services that are independent of any one storage engine.

The application programmer and DBA interact with the MySQL database through Connector APIs and service layers that are above the storage engines. If application changes bring about requirements that demand the underlying storage engine change, or that one or more storage engines be added to support new needs, no significant coding or process changes are required to make things work. The MySQL server architecture shields the application from the underlying complexity of the storage engine by presenting a consistent and easy-to-use API that applies across storage engines.

13.4.1. Pluggable Storage Engine Architecture

MySQL Server uses a pluggable storage engine architecture that enables storage engines to be loaded into and unloaded from a running MySQL server.

Plugging in a Storage Engine

Before a storage engine can be used, the storage engine plugin shared library must be loaded into MySQL using the statement. For example, if the engine plugin is named and the shared library is named , you load it with the following statement:

mysql> INSTALL PLUGIN example SONAME 'ha_example.so';

To install a pluggable storage engine, the plugin file must be located in the MySQL plugin directory, and the user issuing the statement must have privilege for the table.

The shared library must be located in the MySQL server plugin directory, the location of which is given by the system variable.

Unplugging a Storage Engine

To unplug a storage engine, use the statement:

mysql> UNINSTALL PLUGIN example;

If you unplug a storage engine that is needed by existing tables, those tables become inaccessible, but will still be present on disk (where applicable). Ensure that there are no tables using a storage engine before you unplug the storage engine.

13.4.2. The Common Database Server Layer

A MySQL pluggable storage engine is the component in the MySQL database server that is responsible for performing the actual data I/O operations for a database as well as enabling and enforcing certain feature sets that target a specific application need. A major benefit of using specific storage engines is that you are only delivered the features needed for a particular application, and therefore you have less system overhead in the database, with the end result being more efficient and higher database performance. This is one of the reasons that MySQL has always been known to have such high performance, matching or beating proprietary monolithic databases in industry standard benchmarks.

From a technical perspective, what are some of the unique supporting infrastructure components that are in a storage engine? Some of the key feature differentiations include:

Concurrency: Some applications have more granular lock requirements (such as row-level locks) than others. Choosing the right locking strategy can reduce overhead and therefore improve overall performance. This area also includes support for capabilities such as multi-version concurrency control or “snapshot” read.
Transaction Support: Not every application needs transactions, but for those that do, there are very well defined requirements such as ACID compliance and more.
Referential Integrity: The need to have the server enforce relational database referential integrity through DDL defined foreign keys.
Physical Storage: This involves everything from the overall page size for tables and indexes as well as the format used for storing data to physical disk.
Index Support: Different application scenarios tend to benefit from different index strategies. Each storage engine generally has its own indexing methods, although some (such as B-tree indexes) are common to nearly all engines.
Memory Caches: Different applications respond better to some memory caching strategies than others, so although some memory caches are common to all storage engines (such as those used for user connections or MySQL's high-speed Query Cache), others are uniquely defined only when a particular storage engine is put in play.
Performance Aids: This includes multiple I/O threads for parallel operations, thread concurrency, database checkpointing, bulk insert handling, and more.
Miscellaneous Target Features: This may include support for geospatial operations, security restrictions for certain data manipulation operations, and other similar features.

Each set of the pluggable storage engine infrastructure components are designed to offer a selective set of benefits for a particular application. Conversely, avoiding a set of component features helps reduce unnecessary overhead. It stands to reason that understanding a particular application's set of requirements and selecting the proper MySQL storage engine can have a dramatic impact on overall system efficiency and performance.

13.5. The Storage Engine

Before MySQL 5.5.5, is the default storage engine. (The default was changed to in MySQL 5.5.5.) is based on the older (and no longer available) storage engine but has many useful extensions.

Table 13.2. Storage Engine Features

Storage limits	256TB	Transactions	No	Locking granularity	Table
MVCC	No	Geospatial data type support	Yes	Geospatial indexing support	Yes
B-tree indexes	Yes	Hash indexes	No	Full-text search indexes	Yes
Clustered indexes	No	Data caches	No	Index caches	Yes
Compressed data	Yes^[a]	Encrypted data^[b]	Yes	Cluster database support	No
Replication support^[c]	Yes	Foreign key support	No	Backup / point-in-time recovery^[d]	Yes
Query cache support	Yes	Update statistics for data dictionary	Yes

Each table is stored on disk in three files. The files have names that begin with the table name and have an extension to indicate the file type. An file stores the table format. The data file has an () extension. The index file has an () extension.

To specify explicitly that you want a table, indicate that with an table option:

CREATE TABLE t (i INT) ENGINE = MYISAM;

As of MySQL 5.5.5, it is normally necessary to use to specify the storage engine because is the default engine. Before 5.5.5, this is unnecessary because is the default engine unless the default has been changed. To ensure that is used in situations where the default might have been changed, include the option explicitly.

You can check or repair tables with the mysqlcheck client or myisamchk utility. You can also compress tables with myisampack to take up much less space. See Section 4.5.3, “mysqlcheck — A Table Maintenance Program”, Section 4.6.3, “myisamchk — MyISAM Table-Maintenance Utility”, and Section 4.6.5, “myisampack — Generate Compressed, Read-Only MyISAM Tables”.

tables have the following characteristics:

All data values are stored with the low byte first. This makes the data machine and operating system independent. The only requirements for binary portability are that the machine uses two's-complement signed integers and IEEE floating-point format. These requirements are widely used among mainstream machines. Binary compatibility might not be applicable to embedded systems, which sometimes have peculiar processors.
There is no significant speed penalty for storing data low byte first; the bytes in a table row normally are unaligned and it takes little more processing to read an unaligned byte in order than in reverse order. Also, the code in the server that fetches column values is not time critical compared to other code.
All numeric key values are stored with the high byte first to permit better index compression.
Large files (up to 63-bit file length) are supported on file systems and operating systems that support large files.
There is a limit of 2³² (~4.295E+09) rows in a table. If you build MySQL with the option, the row limitation is increased to (2³²)² (1.844E+19) rows. See Section 2.11.3, “Typical configure Options”. Binary distributions for Unix and Linux are built with this option.
The maximum number of indexes per table is 64. This can be changed by recompiling. You can configure the build by invoking configure with the option, where is the maximum number of indexes to permit per table. must be less than or equal to 128.
The maximum number of columns per index is 16.
The maximum key length is 1000 bytes. This can also be changed by changing the source and recompiling. For the case of a key longer than 250 bytes, a larger key block size than the default of 1024 bytes is used.
When rows are inserted in sorted order (as when you are using an column), the index tree is split so that the high node only contains one key. This improves space utilization in the index tree.
Internal handling of one column per table is supported. automatically updates this column for and operations. This makes columns faster (at least 10%). Values at the top of the sequence are not reused after being deleted. (When an column is defined as the last column of a multiple-column index, reuse of values deleted from the top of a sequence does occur.) The value can be reset with or myisamchk.
Dynamic-sized rows are much less fragmented when mixing deletes with updates and inserts. This is done by automatically combining adjacent deleted blocks and by extending blocks if the next block is deleted.
supports concurrent inserts: If a table has no free blocks in the middle of the data file, you can new rows into it at the same time that other threads are reading from the table. A free block can occur as a result of deleting rows or an update of a dynamic length row with more data than its current contents. When all free blocks are used up (filled in), future inserts become concurrent again. See Section 7.10.3, “Concurrent Inserts”.
You can put the data file and index file in different directories on different physical devices to get more speed with the and table options to . See Section 12.1.14, “ Syntax”.
and columns can be indexed.
values are permitted in indexed columns. This takes 0 to 1 bytes per key.
Each character column can have a different character set. See Section 9.1, “Character Set Support”.
There is a flag in the index file that indicates whether the table was closed correctly. If mysqld is started with the option, tables are automatically checked when opened, and are repaired if the table wasn't closed properly.
myisamchk marks tables as checked if you run it with the option. myisamchk --fast checks only those tables that don't have this mark.
myisamchk --analyze stores statistics for portions of keys, as well as for entire keys.
myisampack can pack and columns.

also supports the following features:

Support for a true type; a column starts with a length stored in one or two bytes.
Tables with columns may have fixed or dynamic row length.
The sum of the lengths of the and columns in a table may be up to 64KB.
Arbitrary length constraints.

Additional Resources

13.5.1. Startup Options

The following options to mysqld can be used to change the behavior of tables. For additional information, see Section 5.1.2, “Server Command Options”.

Table 13.3. Option/Variable Reference

Set the mode for automatic recovery of crashed tables.
Don't flush key buffers between writes for any table.
If you do this, you should not access tables from another program (such as from another MySQL server or with myisamchk) when the tables are in use. Doing so risks index corruption. Using does not eliminate this risk.

The following system variables affect the behavior of tables. For additional information, see Section 5.1.4, “Server System Variables”.

Automatic recovery is activated if you start mysqld with the option. In this case, when the server opens a table, it checks whether the table is marked as crashed or whether the open count variable for the table is not 0 and you are running the server with external locking disabled. If either of these conditions is true, the following happens:

The server checks the table for errors.
If the server finds an error, it tries to do a fast table repair (with sorting and without re-creating the data file).
If the repair fails because of an error in the data file (for example, a duplicate-key error), the server tries again, this time re-creating the data file.
If the repair still fails, the server tries once more with the old repair option method (write row by row without sorting). This method should be able to repair any type of error and has low disk space requirements.

If the recovery wouldn't be able to recover all rows from previously completed statements and you didn't specify in the value of the option, automatic repair aborts with an error message in the error log:

Error: Couldn't repair table: test.g00pages

If you specify , a warning like this is written instead:

Warning: Found 344 of 354 rows when repairing ./test/g00pages

Note that if the automatic recovery value includes , the recovery process creates files with names of the form . You should have a cron script that automatically moves these files from the database directories to backup media.

13.5.2. Space Needed for Keys

tables use B-tree indexes. You can roughly calculate the size for the index file as , summed over all keys. This is for the worst case when all keys are inserted in sorted order and the table doesn't have any compressed keys.

String indexes are space compressed. If the first index part is a string, it is also prefix compressed. Space compression makes the index file smaller than the worst-case figure if a string column has a lot of trailing space or is a column that is not always used to the full length. Prefix compression is used on keys that start with a string. Prefix compression helps if there are many strings with an identical prefix.

In tables, you can also prefix compress numbers by specifying the table option when you create the table. Numbers are stored with the high byte first, so this helps when you have many integer keys that have an identical prefix.

13.5.3. Table Storage Formats

supports three different storage formats. Two of them, fixed and dynamic format, are chosen automatically depending on the type of columns you are using. The third, compressed format, can be created only with the myisampack utility (see Section 4.6.5, “myisampack — Generate Compressed, Read-Only MyISAM Tables”).

When you use or for a table that has no or columns, you can force the table format to or with the table option.

See Section 12.1.14, “ Syntax”, for information about .

You can decompress (unpack) compressed tables using myisamchk ; see Section 4.6.3, “myisamchk — MyISAM Table-Maintenance Utility”, for more information.

13.5.3.1. Static (Fixed-Length) Table Characteristics

Static format is the default for tables. It is used when the table contains no variable-length columns (, , , or ). Each row is stored using a fixed number of bytes.

Of the three storage formats, static format is the simplest and most secure (least subject to corruption). It is also the fastest of the on-disk formats due to the ease with which rows in the data file can be found on disk: To look up a row based on a row number in the index, multiply the row number by the row length to calculate the row position. Also, when scanning a table, it is very easy to read a constant number of rows with each disk read operation.

The security is evidenced if your computer crashes while the MySQL server is writing to a fixed-format file. In this case, myisamchk can easily determine where each row starts and ends, so it can usually reclaim all rows except the partially written one. Note that table indexes can always be reconstructed based on the data rows.

Fixed-length row format is only available for tables without or columns. Creating a table with these columns with an explicit clause will not raise an error or warning; the format specification will be ignored.

Static-format tables have these characteristics:

and columns are space-padded to the specified column width, although the column type is not altered. and columns are padded with bytes to the column width.
Very quick.
Easy to cache.
Easy to reconstruct after a crash, because rows are located in fixed positions.
Reorganization is unnecessary unless you delete a huge number of rows and want to return free disk space to the operating system. To do this, use or myisamchk -r.
Usually require more disk space than dynamic-format tables.

13.5.3.2. Dynamic Table Characteristics

Dynamic storage format is used if a table contains any variable-length columns (, , , or ), or if the table was created with the table option.

Dynamic format is a little more complex than static format because each row has a header that indicates how long it is. A row can become fragmented (stored in noncontiguous pieces) when it is made longer as a result of an update.

You can use or myisamchk -r to defragment a table. If you have fixed-length columns that you access or change frequently in a table that also contains some variable-length columns, it might be a good idea to move the variable-length columns to other tables just to avoid fragmentation.

Dynamic-format tables have these characteristics:

All string columns are dynamic except those with a length less than four.
Each row is preceded by a bitmap that indicates which columns contain the empty string (for string columns) or zero (for numeric columns). Note that this does not include columns that contain values. If a string column has a length of zero after trailing space removal, or a numeric column has a value of zero, it is marked in the bitmap and not saved to disk. Nonempty strings are saved as a length byte plus the string contents.
Much less disk space usually is required than for fixed-length tables.
Each row uses only as much space as is required. However, if a row becomes larger, it is split into as many pieces as are required, resulting in row fragmentation. For example, if you update a row with information that extends the row length, the row becomes fragmented. In this case, you may have to run or myisamchk -r from time to time to improve performance. Use myisamchk -ei to obtain table statistics.
More difficult than static-format tables to reconstruct after a crash, because rows may be fragmented into many pieces and links (fragments) may be missing.
The expected row length for dynamic-sized rows is calculated using the following expression:
3 + ( + 7) / 8 + () + () + () + ( + 7) / 8
There is a penalty of 6 bytes for each link. A dynamic row is linked whenever an update causes an enlargement of the row. Each new link is at least 20 bytes, so the next enlargement probably goes in the same link. If not, another link is created. You can find the number of links using myisamchk -ed. All links may be removed with or myisamchk -r.

13.5.3.3. Compressed Table Characteristics

Compressed storage format is a read-only format that is generated with the myisampack tool. Compressed tables can be uncompressed with myisamchk.

Compressed tables have the following characteristics:

Compressed tables take very little disk space. This minimizes disk usage, which is helpful when using slow disks (such as CD-ROMs).
Each row is compressed separately, so there is very little access overhead. The header for a row takes up one to three bytes depending on the biggest row in the table. Each column is compressed differently. There is usually a different Huffman tree for each column. Some of the compression types are:
- Suffix space compression.
- Prefix space compression.
- Numbers with a value of zero are stored using one bit.
- If values in an integer column have a small range, the column is stored using the smallest possible type. For example, a column (eight bytes) can be stored as a column (one byte) if all its values are in the range from to .
- If a column has only a small set of possible values, the data type is converted to .
- A column may use any combination of the preceding compression types.
Can be used for fixed-length or dynamic-length rows.

While a compressed table is read only, and you cannot therefore update or add rows in the table, DDL (Data Definition Language) operations are still valid. For example, you may still use to drop the table, and to empty the table.

13.5.4. Table Problems

The file format that MySQL uses to store data has been extensively tested, but there are always circumstances that may cause database tables to become corrupted. The following discussion describes how this can happen and how to handle it.

13.5.4.1. Corrupted Tables

Even though the table format is very reliable (all changes to a table made by an SQL statement are written before the statement returns), you can still get corrupted tables if any of the following events occur:

The mysqld process is killed in the middle of a write.
An unexpected computer shutdown occurs (for example, the computer is turned off).
Hardware failures.
You are using an external program (such as myisamchk) to modify a table that is being modified by the server at the same time.
A software bug in the MySQL or code.

Typical symptoms of a corrupt table are:

You get the following error while selecting data from the table:
Incorrect key file for table: '...'. Try to repair it
Queries don't find rows in the table or return incomplete results.

You can check the health of a table using the statement, and repair a corrupted table with . When mysqld is not running, you can also check or repair a table with the myisamchk command. See Section 12.4.2.2, “ Syntax”, Section 12.4.2.5, “ Syntax”, and Section 4.6.3, “myisamchk — MyISAM Table-Maintenance Utility”.

If your tables become corrupted frequently, you should try to determine why this is happening. The most important thing to know is whether the table became corrupted as a result of a server crash. You can verify this easily by looking for a recent message in the error log. If there is such a message, it is likely that table corruption is a result of the server dying. Otherwise, corruption may have occurred during normal operation. This is a bug. You should try to create a reproducible test case that demonstrates the problem. See Section C.5.4.2, “What to Do If MySQL Keeps Crashing”, and MySQL Internals: Porting.

13.5.4.2. Problems from Tables Not Being Closed Properly

Each index file ( file) has a counter in the header that can be used to check whether a table has been closed properly. If you get the following warning from or myisamchk, it means that this counter has gone out of sync:

clients are using or haven't closed the table properly

This warning doesn't necessarily mean that the table is corrupted, but you should at least check the table.

The counter works as follows:

The first time a table is updated in MySQL, a counter in the header of the index files is incremented.
The counter is not changed during further updates.
When the last instance of a table is closed (because a operation was performed or because there is no room in the table cache), the counter is decremented if the table has been updated at any point.
When you repair the table or check the table and it is found to be okay, the counter is reset to zero.
To avoid problems with interaction with other processes that might check the table, the counter is not decremented on close if it was zero.

In other words, the counter can become incorrect only under these conditions:
