Thanks for bringing this out! My first question when quickly looking at this is can we make the CompressionInfo change agnostic to the algorithm or have the format change based off the algorithm? Lz4 has similar (though not as easy to use as zstd) feature and new algorithms might come out whic

Hi Andres, This looks like a great CEP. Having official, source-controlled code within Cassandra (or a sidecar in this case) to handle common operator actions would centralize best practices and make the operator experience smoother—especially for users who may not have deep Cassandra expertise

Thanks for the CEP! It fills the gaps of CEP-40 as well. A small question from my side: I see that the underlying assumption is that Sidecar is able to query Cassandra instances before bouncing/recognizing the bounce. What if it could not communicate with the Cassandra instance (e.g., binary proto
