Yibo Cai created ARROW-9344: ------------------------------- Summary: [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
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)
