Redis is an open source, in-memory data structure store, used as database, cache and message broker.
The version currently installed by the add-on is : Redis 4.0.2
Redis administration with Redsmin
Each Redis add-on provides a Redsmin dasboard, which allows you to query and monitor your redis database activity.
Redis databases are backed up once a day. You can download backups from the ad-don panel
(in the "backups" tab). A backup is a
tar.gz archive containing both the
.aof files. You can extract this archive and run
redis-server in the extracted folder
to access data.
Leader / follower topology
By default, all redis add-ons are configured as leaders. You can set up a redis add-on as a follower from the add-on panel (in the "Add-on information" tab). You need to set the leader information (host, port, password) to start the replication. The add-on panel will display the sync process status so that you know when the synchronisation is done.
While a redis database is configured as a follower, it's read-only.
Default retention policy
By default, the eviction policy is
noeviction. If you plan to use Redis as a LRU cache,
please contact the support to change its policy.
