Re: Dropwizard/Codahale metrics deprecation in Cassandra server

2025-03-12 Thread Benedict
It sounds like for the original query we have a broad consensus:1) Deprecate Codahale, but for the next major version publish compatible metrics2) After the next release, move to a codahale-like registry that allows us to be efficient without abusing unsafe, and continue publishing metrics that imp

Basically but ideally we would stop writing the old sketches once we’ve updated all the existing sstables to the new ones. I think ideally this would be orthogonal to sstable version, so that we can drop new sketches in place to existing sstables as we are able to produce them, and we can stop writ

Interesting. So to repeat that if I got it right: current format - serialized Clearspring log next format - serialized Clearspring log PLUS serialized log from Datasketches in case all SSTables are on legacy format - merge all Clearspring logs in case some SSTables are on legacy format and the re

Benedict, I have reached Datasketches community (1) and asked what they think about Clearspring and if it is convertible to Datasketches as you earlier suggested that we might try to convert one to the other. Based on what they wrote, I do not think that is possible to do (2) and they say that Cl
