Kurt Greaves commented on CASSANDRA-12649: ------------------------------------------ Would be nice to see this committed. We have seen a lot of users mistakenly batch against multiple partitions. > Add BATCH metrics > ----------------- > > Key: CASSANDRA-12649 > URL: https://issues.apache.org/jira/browse/CASSANDRA-12649 > Project: Cassandra > Issue Type: Wish > Reporter: Alwyn Davis > Priority: Minor > Fix For: 3.x > > Attachments: trunk-12649.txt > > > To identify causes of load on a cluster, it would be useful to have some > additional metrics: > * *Mutation size distribution:* I believe this would be relevant when > tracking the performance of unlogged batches. > * *Logged / Unlogged Partitions per batch distribution:* This would also give > a count of batch types processed. Multiple distinct tables in batch would > just be considered as separate partitions. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
