reloading configuration without restarting

[Dvir Volk]

hey all

is there a way to reload a redis configuration without restarting the server?

the documentation and a quick look at the code suggests that no.

if there isn't, is it safe to iterate over a redis.conf file and simple issue a CONFIG SET command for each line?

I don't think so, not all the config parameters are supported, and I
would pay particular attention to persistence...
Better to check with CONFIG GET is everything is fine and only change
the parameters when needed but there must be some logic to avoid
problems.

thanks.

is it possible to simply add  something like CONFIG RELOAD to redis, that just calls loadServerConfig()?

or will it break stuff if done during operation?

Not planned for now, it is uncertain if we'll take this step or the
reverse CONFIG WRITE after hackig with CONFIG SET.
It's a good idea but we'll have to study it better before implementing.

Currently the solution is to use CONFIG SET and to change by hand the
configuration in redis.conf.
