Re: Recycled-Commitlogs

[Jeff Jirsa]

What version of cassandra is this?  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?

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
