refs https://github.com/TryGhost/Toolbox/issues/515 - This implementation allows to use Redis cluster as a caching adapter. The cache adapter can be configured through same adapter configuration interface as others. It accepts following config values: - "ttl" - time in SECONDS for stored entity to live in Redis cache - "keyPrefix" - special cache key prefix to use with stored entities - "host" / "port" / "password" / "clusterConfig" - Redis instance specific configs - Set test coverage to non-standard 75% because the code mostly consists of the glue code that would require unnecessary Redis server mocking and would be a bad ROI. This module has been used in production for a long time already, so can be considered pretty stable.
