Provides access to a redis cluster.

Dynamic options:

Static options:

Name Description Default value
thread_pools.redis_thread_pool_size thread count to serve Redis requests -
thread_pools.sentinel_thread_pool_size thread count to serve sentinel requests. -
groups array of redis clusters to work with excluding subscribers -
groups.[].config_name key name in secdist with options for this cluster -
groups.[].db name to refer to the cluster in components::Redis::GetClient() -
groups.[].sharding_strategy one of RedisCluster, KeyShardCrc32, KeyShardTaximeterCrc32 or KeyShardGpsStorageDriver "KeyShardTaximeterCrc32"
groups.[].allow_reads_from_master allows read requests from master instance false
subscribe_groups array of redis clusters to work with in subscribe mode -
subscribe_groups.[].config_name key name in secdist with options for this cluster -
