When a client disconnects, the client's threads are put in the cache (unless it is full). As of MySQL 5.6.8, default thread cache size depends on the value of [max_connections](https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_max_connections) and is capped at 100 threads. Requests for threads are satisfied by reusing threads taken from the cache if possible, and only when the cache is empty is a new thread created.\n\n**Threads Cached** is the number of threads in the thread cache.\n\n**Threads Created** is the number of threads created to handle connections.",

                    "description": "Shows various uses of memory within MySQL.\n\n**System Memory** is the total memory for the system.\n\n**InnoDB Buffer Pool Data** is the size of the [InnoDB buffer pool](https://dev.mysql.com/doc/refman/5.7/en/innodb-buffer-pool.html) for caching data and indexes in memory.\n\n**TokuDB Cache Size** is the size of the [TokuDB cache table](https://www.percona.com/doc/percona-server/LATEST/tokudb/tokudb_variables.html#tokudb_cache_size). For more information, see [Considerations to Run TokuDB in Production](https://www.percona.com/doc/percona-server/LATEST/tokudb/tokudb_quickstart.html#considerations-to-run-tokudb-in-production)\n\n**Key Buffer Size** is the size of the [buffer used for index blocks](https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_key_buffer_size) in MyISAM tables. The key buffer is also known as the *key cache*.\n \n**Adaptive Hash Index Size** is the size of the [adaptive hash index](https://dev.mysql.com/doc/refman/5.7/en/innodb-adaptive-hash.html), which enables InnoDB to perform more like an in-memory database. When InnoDB notices that some index values are being accessed very frequently, it builds a hash index for them in memory on top of B-Tree indexes. This allows for very fast hashed lookups.\n\n**Query Cache Size** is the size of the [MySQL query cache](https://dev.mysql.com/doc/refman/5.7/en/query-cache.html), which stores the text of a `SELECT` statement together with the corresponding result that was sent to the client. The query cache has huge scalability problems, because only one thread can do an operation in the query cache at a time. This serialization is true for `SELECT`, `INSERT`, `UPDATE`, and `DELETE` queries. The larger the query cache size is set to, the slower those operations become.\n\n**InnoDB Dictionary Size** is the size of the [InnoDB data dictionary](https://dev.mysql.com/doc/refman/5.7/en/innodb-data-dictionary.html), which is the internal catalog of tables. InnoDB stores the data dictionary on disk, and loads entries into memory while the server is running. This is somewhat analogous to MySQL\u2018s table cache, but instead of operating at the server level, it is internal to the InnoDB storage engine.\n\n**InnoDB Log Buffer Size** the size of the [InnoDB redo log buffer](https://dev.mysql.com/doc/refman/5.6/en/innodb-redo-log-buffer.html). It allows transactions to run without having to write the log to disk until the transaction commits.",
