FLUSHALL

FLUSHALL

FLUSHALL [ASYNC | SYNC]

Available since: 1.0.0
Time complexity: O(N) where N is the total number of keys in all databases
ACL categories: @keyspace, @write, @slow, @dangerous

Delete all the keys of all the existing databases, not just the currently selected one. This command never fails.

By default, FLUSHALL will synchronously flush all the databases. Starting with Redict 6.2, setting the lazyfree-lazy-user-flush configuration directive to “yes” changes the default flush mode to asynchronous.

It is possible to use one of the following modifiers to dictate the flushing mode explicitly:

ASYNC: flushes the databases asynchronously
!SYNC: flushes the databases synchronously

Note: an asynchronous FLUSHALL command only deletes keys that were present at the time the command was invoked. Keys created during an asynchronous flush will be unaffected.
