Cassandra consuming lot of memory

Hi Folks

We are using Cassandra as the database for our Temporal deployment. We’ve noticed that in the last one week since we went live, the Cassandra’s memory has constantly gone up. I understand this is not Temporal specific issue but was wondering if you ever experienced any such behaviour and if there are any Temporal knobs that we can tweak.

We’ve experienced same behaviour with both of the following Cassandra config

  1. 4CPU 16GB 3 Node cluster
  2. 8CPU 32GB 3 Node cluster
