Configuring Redis

Configuring Redis can significantly improve Addok.

Generic tips from the official doc this topic.

See also the configuration reference.

On Linux, the default configuration file path is /etc/redis/redis.conf.


To be able to stop and start Redis without needing a new import, it's important to let Redis persist the data on disk. By default, Redis will persist data every x time or every x changes in the data. The best thing is to totally disable automatic persistence, and do it by hand when needed. In fact, only after import we need to persist the data. When Addok is running, there is not need to persist (addok will create some temporary keys from time to time, but they are volatile).

To deactivate auto save for the running instance, type:

redis-cli config set save ""

If you want to do it for good, comment the save lines in the redis conf.

This is the perfect setting for running Addok. But remember that the configuration if for the Redis instance, so if you have other services than Addok using it, you may configure it your way.


When importing data, you need to persist it, so a restart of Redis will reload it.

You can either:

  • keep the normal redis save configuration, which will persist on the fly while importing. This will make the import a bit slower, and consume a bit more memory during the import.
  • issue a redis-cli bgsave after the import: this is the faster scenario, because Redis will be ready to use just after the import, bgsave being asynchronous. But this will use more or less the double memory when doing the bgsave, because Redis will create a subprocess;
  • issue a redis-cli save, which is synchronous: this will block Redis for one or two minutes (depending on the data you imported), but there is no extra memory usage
