How can you disable snapshotting on a running Redis instance?
You can disable the "save" setting in the Redis configuration by commenting out the "save" lines. E.g.,
#save 900 1
#save 300 10
#save 60 10000
However, Redis lacks a command to reload its configuration without restarting. How can I remove the "save" settings from a running instance of Redis? There seems to be no CONFIG DEL or CONFIG UNSET commands, and I didn't see anything related to this in CONFIG GET or CONFIG SET.
If you try inspecting the value of the "save" setting, you'll notice it's a single string value containing each save point:
> CONFIG GET save
1) "save"
2) "900 1 300 10 60 10000"
According to the Redis configuration file redis.conf:
It is also possible to remove all the previously configured save points by adding a save directive with a single empty string argument like in the following example:
save ""
So to disable snapshotting you can remove those save points by setting its value to an empty string:
> CONFIG SET save ""
OK
> CONFIG GET save
1) "save"
2) ""
