That would only work for single-node Redis, not Cluster. Tunneling would break the inter-node protocol it uses on port 10000. 2) Write Redis in Python with C libraries. Simple strings start with a +and run until end of line (CRLF, \r\n). It encapsulates an actual TCP connection to a Redis server and sends raw commands, as bytes serialized using the REdis Serialization Protocol (RESP), to the server. To fix this issue, we obviously wanted to reduce the amount of traffic between our server nodes and cache. Since 3.4, MongoDB has used wire protocol compression for traffic between servers. It must have a different value than db. The module issues LPOP commands using the Redis Protocol to pull data.
