Michael updated CASSANDRA-15127: -------------------------------- Component/s: Observability/Metrics > Add compression performance metrics > ----------------------------------- > > Key: CASSANDRA-15127 > URL: https://issues.apache.org/jira/browse/CASSANDRA-15127 > Project: Cassandra > Issue Type: Task > Components: Observability/Metrics > Reporter: Michael > Priority: Normal > > When doing some bulk load into my cluster I notice almost 100% CPU usage. > As I am using DeflateCompressor, I assume that the data > compression/decompression contributes a lot to overall CPU load. > Unfortunately cassandra doesn't seem to have any metrics explaining how much > CPU time has been required for that. > So I guess it would be useful to introduce cumulative times for compression > and decompression, breaking down by each supported compression algorithm. > Then by comparing how much does each specific value increase per minute, with > number of processed requests and their cumulative times, it would be easy to > conclude how costly is the compression. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
