Instruct Redis to start an Append Only File rewrite process. The rewrite will create a small optimized version of the current Append Only File.
If BGREWRITEAOF
fails, no data gets lost as the old AOF will be untouched.
The rewrite will be only triggered by Redis if there is not already a background process doing persistence. Specifically:
BGREWRITEAOF
will still return an OK code, but with an appropriate message. You can check if an AOF rewrite is scheduled looking at the INFO
command as of Redis 2.6.Since Redis 2.4 the AOF rewrite is automatically triggered by Redis, however the BGREWRITEAOF
command can be used to trigger a rewrite at any time.
Please refer to the persistence documentation for detailed information.
