Ending Support for Redis Caching Backplane Published Aug 31, 2023 If your Rock instance does not use Redis, then you can skip this article. As stated before, maintaining old code is a costly endeavor. So, starting with Rock v17, we're removing support for the original Redis backplane. Originally, Redis was used by some very large churches to maintain a cache of data across multiple Rock instances. However, with the introduction of the Rock Web Farm and a message bus in v12, Rockʼs internal cache was able to be synchronized across all the nodes in a Rock server farm. If you would like more information about Rockʼs Web Farm feature, see our Hyper Scaling Rock guide.
