- [FLUSH](/docs/server/reference/sql-statements/administrative-sql-statements/flush-commands/flush.md): Complete FLUSH statement reference: NO\_WRITE\_TO\_BINLOG/LOCAL syntax, FLUSH TABLES WITH READ LOCK/FOR EXPORT, FLUSH STATUS, and SSL/TLS certificate reload.
- [FLUSH QUERY CACHE](/docs/server/reference/sql-statements/administrative-sql-statements/flush-commands/flush-query-cache.md): Defragment the query cache to optimize memory usage. This command reorganizes the cache to eliminate fragmentation without removing existing cached queries.
- [FLUSH TABLES FOR EXPORT](/docs/server/reference/sql-statements/administrative-sql-statements/flush-commands/flush-tables-for-export.md): Prepare individual tables for binary backup. This command flushes changes to disk and locks tables, allowing safe copying of .ibd files while the server runs.
