Brandon Williams commented on CASSANDRA-8195: --------------------------------------------- Have you seen CASSANDRA-7974? > Tools for discovering problem/largest partitions > ------------------------------------------------ > > Key: CASSANDRA-8195 > URL: https://issues.apache.org/jira/browse/CASSANDRA-8195 > Project: Cassandra > Issue Type: Improvement > Reporter: Matt Stump > > A very common problem is that a customer will have one or two very hot > partitions. This could be a result of an unforeseen usage pattern or a > problem user. Tracking down the offending parition/row currently involves a > linear scan of the data. > We should keep stats on the largest N partitions encountered and make those > visible via nodetool as we do with cfhistograms. A reasonable suggestion for > N is 10, meaning the top 10 partition keys and their size would be visible. > We should also probably keep this info as part of the sstable metadata. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
