Well, I do have a confession to make. It is actually scyllaDB and the latest version. As it is (generally) Cassandra compatible I naturally assumed that these items were in both applications.

Recycling segments was a thing from like 1.1 to 2.2 but really very different in modern versions (and cdc / point in time backup mirrors some of the concepts around hanging onto segments) Knowing the version would be super helpful though Is this … 1.2? 2.0?

One of our nodes has thousands of -rw-r--r-- 1 root root 33554432 Jun 24 15:11 Recycled-CommitLog-2-67041997483.log hanging around. Eventually they fill the filesystem. I have searched around and can find no mention of these recycled commits. Can anyone explain what they are for? Can I purge these in some graceful fashion with a service restart, a simple deletion, or a complete drain/restart of the node? Thanks Marc
