I host a Rails 5 website that uses Sidekiq to manage its background jobs. The problem I have is that regularly the appendonly.aof file grows to big that it fills that whole disk where it is saved.
It there a way to limit the size of appendonly.aof ?
My redis.conf file is pretty standard

Refer to https://redislabs.com/ebook/part-2-core-concepts/chapter-4-keeping-data-safe-and-ensuring-performance/4-1-persistence-options/4-1-3-rewritingcompacting-append-only-files/
With
auto-aof-rewrite-percentage
andauto-aof-rewrite-min-size
options, you should be able to have a handle on the size.You can also execute command
BGREWRITEAOF
in your redis-cli to trigger it manually.
