Configuring Redis Cluster

Note: If you are using Enterprise Redis, this needs to be configured to use a custom hashing policy, with the following regular expression as rule one:

^[^{]*?\{(?<tag>[^}]+?)\}.*$

See the Database clustering page of the Redis Enterprise documentation for more information on the custom hashing policy.

Enterprise Server supports Redis Cluster as a Scale-Out Repository (SOR). Redis Cluster is a distributed implementation of Redis with performance, scalability, and availability as part of its design. You can configure communication with Redis Cluster by setting the environment variable MFREDIS_CONFIG to point to a configuration file. This configuration file can contain the following variables:

RD_LUA_LOG

This variable enables logging of Lua scripts on the Redis server.

Note: The Redis server must be started with --log-level set to warning as a minimum.

ON: Enables logging.
OFF: Disables logging.

The default value is OFF.

RD_RETRY_INTERVAL

Specifies how long, in milliseconds, the Redis client should wait before reattempting to connect and perform the last failed request.

The default value is 2000 (2 seconds).

RD_RETRY_ATTEMPTS

Specify the number of attempts the Redis client should try to perform the last failed request.

The default value is 1.
