Blake Eggleston updated CASSANDRA-13373: ---------------------------------------- Reviewer: Blake Eggleston > Provide additional speculative retry statistics > ----------------------------------------------- > > Key: CASSANDRA-13373 > URL: https://issues.apache.org/jira/browse/CASSANDRA-13373 > Project: Cassandra > Issue Type: Improvement > Components: Observability > Reporter: Ariel Weisberg > Assignee: Ariel Weisberg > Fix For: 4.x > > > Right now there is a single metric for speculative retry on reads that is the > number of speculative retries attempted. You can't tell how many of those > actually succeeded in salvaging the read. > The metric is also per table and there is no keyspace level rollup as there > is for several other metrics. > Add a metric that counts reads that attempt to speculate but fail to complete > before the timeout (ignoring read errors). > Add a rollup metric for the current count of speculation attempts as well as > the count of failed speculations. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
