David Li resolved ARROW-9344. ----------------------------- Fix Version/s: 2.0.0 Resolution: Fixed Issue resolved by pull request 7863 [https://github.com/apache/arrow/pull/7863] > [C++][Flight] measure latency quantile in flight benchmark > ---------------------------------------------------------- > > Key: ARROW-9344 > URL: https://issues.apache.org/jira/browse/ARROW-9344 > Project: Apache Arrow > Issue Type: Improvement > Components: C++, FlightRPC > Reporter: Yibo Cai > Assignee: Yibo Cai > Priority: Major > Labels: pull-request-available > Fix For: 2.0.0 > > Time Spent: 1h > Remaining Estimate: 0h > > ARROW-9206 measures average latency in flight benchmark. > In practice, latency quantile is necessary to show the whole picture of rpc > performance. E.g., 99% quantile, max, median. > A naive approach to save latencies of all batches is not applicable. Boost > accumulator_set implements p square quantile algorithm which uses O(1) space > with trivial computation overhead for each batch. It can be used in > calculating latency quantiles. -- This message was sent by Atlassian Jira (v8.3.4#803005)
