Subject [jira] [Commented] (CASSANDRA-11865) Improve compaction logging details
Date Fri, 20 May 2016 21:26:12 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11865?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15294263#comment-15294263
] 

Chris Lohfink commented on CASSANDRA-11865:
-------------------------------------------

Just curious, cant you figure out the partition min/max/avg size from the input/output sstables
partition size histograms?

Same for most the info kept in stats metadata, encoding stats, and compaction metadata. Although
the historical context of sstables that no longer exist could be useful.

> I'd like to see per compaction entry:
>   * Partitions processed
>   * Rows processed
>   * Partition merge stats
>   * If a wide row was detected
>   * The partition min/max/avg size
>   * The min/max/avg row count across partitions
> Anything else [~krummas]?
