text: It is broken into two parts: installation and setup, and then references to specific Redis wrappers.Installation and Setupâ€‹Install the Redis Python SDK with pip install redisWrappersâ€‹All wrappers needing a redis url connection string to connect to the database support either a stand alone Redis server
  or a High-Availability setup with Replication and Redis Sentinels.Redis Standalone connection urlâ€‹For standalone Redis server the official redis connection url formats can be used as describe in the python redis modules
  "from_url()" method Redis.from_urlExample: redis_url = "redis://:secret-pass@localhost:6379/0"Redis Sentinel connection urlâ€‹For Redis sentinel setups the connection scheme is "redis+sentinel".
  This is an un-offical extensions to the official IANA registered protocol schemes as long as there is no connection url
  for Sentinels available.Example: redis_url = "redis+sentinel://:secret-pass@sentinel-host:26379/mymaster/0"The format is  redis+sentinel://[[username]:[password]]@[host-or-ip]:[port]/[service-name]/[db-number]
  with the default values of "service-name = mymaster" and "db-number = 0" if not set explicit.
  The service-name is the redis server monitoring group name as configured within the Sentinel. The current url format limits the connection string to one sentinel host only (no list can be given) and
  booth Redis server and sentinel must have the same password set (if used).Redis Cluster connection urlâ€‹Redis cluster is not supported right now for all methods requiring a "redis_url" parameter.
  The only way to use a Redis Cluster is with LangChain classes accepting a preconfigured Redis client like RedisCache
