Sam Tunnicliffe updated CASSANDRA-8627:
---------------------------------------
Component/s: Observability
> Support Total/Recent latency histogram metrics for range slices
> ---------------------------------------------------------------
>
> Key: CASSANDRA-8627
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8627
> Project: Cassandra
> Issue Type: Improvement
> Components: Observability
> Reporter: Chris Lohfink
> Assignee: Sam Tunnicliffe
> Labels: metrics
> Fix For: 2.1.3
>
> Attachments: 8627.txt
>
>
> The Metrics histogram is pretty bad at non-normal data like latencies and
> (empirically tested and theoretically) is untrustworthy at 99th percentile.
> For applications that care about the percentiles having the more
> statistically accurate version is beneficial. Adding the deprecated methods
> like other latency histograms for CASSANDRA-7338 temporarily would help.
> This is just for 2.1 branch. CASSANDRA-5657 solves everything in 3.0.
