Aleksey Yeschenko updated CASSANDRA-8662: ----------------------------------------- Reviewer: Aleksey Yeschenko > Switch cfhistograms from using yammer metrics in 2.1 > ---------------------------------------------------- > > Key: CASSANDRA-8662 > URL: https://issues.apache.org/jira/browse/CASSANDRA-8662 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Chris Lohfink > Assignee: Chris Lohfink > Fix For: 2.1.3 > > Attachments: CASSANDRA-8662v1.txt > > > cfhistograms was changed to use the yammer histograms CASSANDRA-5871. Until > CASSANDRA-5657's change to metrics we shouldn't represent the yammer > histogram for latency metrics. Yammer's histogram is based on assumption of > a normal distribution and is bad at representing the tail percentiles with > skewed distributions. So revert the change just in the 2.1 branch but leave > it for 3.0. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
