System variables that are true or false can be enabled at server startup by naming them, or disabled by using a --skip- prefix. Many system variables can be changed at runtime see Section 5. For information about GLOBAL and SESSION variable scope modifiers, refer to the SET statement documentation. Certain options control the locations and layout of the InnoDB data files.
Section Some options, which you might not use initially, help tune InnoDB performance characteristics based on machine capacity and your database workload. For more information on specifying options and system variables, see Section 4.
Controls loading of the InnoDB storage engine, if the server was compiled with InnoDB support. This option has a tristate format, with possible values of OFFONor FORCE. See Section 5. In this case, because the default storage engine is InnoDBthe server does not start unless you also use --default-storage-engine and --default-tmp-storage-engine to set the default to some other engine for both permanent and TEMPORARY tables.
Their use results in a warning. Expect these options to be removed in a future MySQL release. pid in the data directory and writes SHOW ENGINE INNODB STATUS output to it every 15 seconds, approximately. pid file is not created by default. To create it, start mysqld with the --innodb-status-file option. InnoDB removes the file when the server is shut down normally.
If an abnormal shutdown occurs, the status file may have to be removed manually. pid file can become quite large over how to write a good application 0 with a slash. For related information, see Section Disable the InnoDB storage engine, how to write a good application 0 with a slash.
See the description of --innodb. This option can only be set at server startup. You must also enable the MySQL binary log on the source server using the --log-bin option. For more information, see Section Specifies the shared library that implements the InnoDB memcached plugin.
The path of the directory containing the shared library that implements the InnoDB memcached plugin. The default value is NULL, representing the MySQL plugin directory. You should not need to modify this parameter unless specifying a memcached plugin for a different storage engine that is located outside of the MySQL plugin directory. Used to pass space-separated memcached options to the underlying memcached memory object caching daemon on startup.
For example, you might change the port that memcached listens on, reduce the maximum number of simultaneous connections, change the maximum memory size for a key-value pair, or enable debugging messages for the error log. See Section For information about memcached options, refer to the memcached man page. Specifies how many memcached read operations get operations to perform before doing a COMMIT how to write a good application 0 with a slash start a new transaction.
This value is set to 1 by default, so that any changes made to the table through SQL statements are immediately visible to memcached operations. You might increase it to reduce the overhead from frequent commits on a system where the underlying table is only being accessed through the memcached interface.
If you set the value too large, the amount of undo or redo data could impose some storage overhead, as with any long-running transaction. Specifies how many memcached write operations, such as addsetand incrto perform before doing a COMMIT to start a new transaction. This value is set to 1 by default, on the assumption that data being stored is important to preserve in case of an outage and should immediately be committed.
When storing non-critical data, you might increase this value to reduce the overhead from frequent commits; but then the last N -1 uncommitted write operations could be lost if an unexpected exit occurs. Specifies whether to dynamically adjust the rate of flushing dirty pages in the InnoDB buffer pool based on the workload. This setting is enabled by default. Defines the low water mark representing percentage of redo log capacity at which adaptive flushing is enabled.
Whether the InnoDB adaptive hash index is enabled or disabled. It may be desirable, depending on your workload, to dynamically enable or disable adaptive hash indexing to improve query performance. Because the adaptive hash index may not be useful for all workloads, conduct benchmarks with it both enabled and disabled, using realistic workloads. This variable is enabled by default.
You can modify this parameter using the SET GLOBAL statement, without restarting the server. Changing the setting at runtime requires privileges sufficient to set global system variables. You can also use --skip-innodb-adaptive-hash-index at server startup to disable it. Disabling the adaptive hash index empties the hash table immediately. Normal operations can continue while the hash table is emptied, and executing queries that were using the hash table access the index B-trees directly instead.
When the adaptive hash index is re-enabled, the hash table is populated again during normal operation. Partitions the adaptive hash index search system. Each index is bound to a specific partition, with each partition protected by a separate latch. The adaptive hash index search system is partitioned into 8 parts by default. The maximum setting is The value represents the number of microseconds. This option can be useful in busy systems, with greater than 16 InnoDB threads.
In practice, it is most valuable for MySQL systems with hundreds or thousands of simultaneous connections. How often to auto-commit idle connections that use the InnoDB memcached interface, in seconds.
Use this option to disable row locks when InnoDB memcached performs DML operations. It must be specified on the mysqld command line or entered in the MySQL configuration file. Configuration takes effect when the plugin is installed, which occurs when the MySQL server is started.
Lets you use the InnoDB memcached plugin with the MySQL binary log. For more information, see Enabling the InnoDB memcached Binary Log, how to write a good application 0 with a slash. Locks the table used by the InnoDB memcached plugin, so that it cannot be dropped or altered by DDL through the SQL interface. Controls the transaction isolation level on queries processed by the memcached interface. The constants corresponding to the familiar names are:.
The increment size in megabytes for extending the size of an auto-extending InnoDB system tablespace file when it becomes full. The default value is For related information, see System Tablespace Data File Configurationand Resizing the System Tablespace.
The initial extensions are by small amounts, after which extensions occur in increments of 4MB. The lock mode to use for generating auto-increment values, how to write a good application 0 with a slash.
Permissible values are 0, 1, or 2, for traditional, consecutive, or interleaved, respectively. The default setting is 2 interleaved as of MySQL 8. The change to interleaved lock mode as the default setting reflects the change from statement-based to row-based replication as the default replication type, which occurred in MySQL 5.
Statement-based replication requires the consecutive auto-increment lock mode to ensure that auto-increment values are assigned in a predictable and repeatable order for a given sequence of SQL statements, whereas row-based replication is not sensitive to the execution order of SQL statements. For example, if test case A places table t1 on the background drop list, test case B waits until the background drop list is empty before creating table t1.
The adjustment how to write a good application 0 with a slash when the buffer pool is initialized. Specifies whether to record the pages cached in the InnoDB buffer pool when the MySQL server is shut down, to shorten the warmup process at the next restart.
Immediately records the pages cached in the InnoDB buffer pool. Specifies the percentage of the most recently used pages for each buffer pool to read out and dump.
The range is 1 to A non-default location must be specified relative to the data directory. A file name can be specified at runtime, using a SET statement:. You can also specify a file name at startup, in a startup string or MySQL configuration file. When specifying a file name at startup, the file must exist or InnoDB returns a startup error indicating that there is no such how to write a good application 0 with a slash or directory.
The number of regions that the InnoDB buffer pool is divided into. For systems with buffer pools in the multi-gigabyte range, dividing the buffer pool into separate instances can improve concurrency, by reducing contention as different threads read and write to cached pages.
Each page that is stored in or read from the buffer pool is assigned to one of the buffer pool instances randomly, using a hashing function. Each buffer pool manages its own free lists, flush listsLRUsand all other data structures connected to a buffer pool, and is protected by its own buffer pool mutex.
The total buffer pool size is divided among all the buffer pools. Otherwise, the default is 1. Specifies that, on MySQL server startup, the InnoDB buffer pool is automatically warmed up by loading the same pages it held at an earlier time.
Immediately warms up the InnoDB buffer pool by loading a set of data pages, without waiting for a server restart. Can be useful to bring cache memory back to a known state during benchmarking, or to ready the MySQL server to resume its normal workload after running queries for reports or maintenance.
The size in bytes of the buffer poolthe memory area where InnoDB caches table and index data. The default value is bytes MB.
