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 Redis 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.
