FLUSH TABLES

Read lock all tables across all databases and make all other MemSQL connections block when they try to modify these tables.

Syntax

FLUSH TABLES WITH READ LOCK

Remarks

  • FLUSH TABLES will lock and then flush all remaining write transactions in the current database to disk.
  • You need to UNLOCK TABLES before you can modify or write to tables locked by this command in the current MemSQL database.
  • This command must be run on the master aggregator node or a child aggregator node (see Node Requirements for MemSQL Commands ).

Example

memsql> FLUSH TABLES WITH READ LOCK;
Query OK, 0 rows affected (0.00 sec)
