Chinmay Kulkarni updated PHOENIX-5981: -------------------------------------- Attachment: PHOENIX-5981-4.x-v2.patch > Wrong multiple counting of resultSetTimeMs and wallclockTimeMs in > OverallQueryMetrics > ------------------------------------------------------------------------------------- > > Key: PHOENIX-5981 > URL: https://issues.apache.org/jira/browse/PHOENIX-5981 > Project: Phoenix > Issue Type: Bug > Affects Versions: 4.15.0 > Reporter: Chinmay Kulkarni > Assignee: Chinmay Kulkarni > Priority: Major > Labels: metrics, phoenix-hardening, quality-improvement > Fix For: 4.16.0 > > Attachments: PHOENIX-5981-4.x-v1.patch, PHOENIX-5981-4.x-v2.patch, > PHOENIX-5981-master-v1.patch > > Time Spent: 20m > Remaining Estimate: 0h > > We update wallClockTimeMS and resultSetTimeMS when we reach the last row in > our ResultSet iterations (see > [this|https://github.com/apache/phoenix/blob/dcc88af8acc2ba8df10d2e9d498ab3646fdf0a78/phoenix-core/src/main/java/org/apache/phoenix/jdbc/PhoenixResultSet.java#L878-L881]). > However, this is also called inside PhoenixResultSet.close(), see > [this|https://github.com/apache/phoenix/blob/dcc88af8acc2ba8df10d2e9d498ab3646fdf0a78/phoenix-core/src/main/java/org/apache/phoenix/jdbc/PhoenixResultSet.java#L214-L215]. > The problem is, these calls in-turn add elapsedTime again > ([endQuery|https://github.com/apache/phoenix/blob/dcc88af8acc2ba8df10d2e9d498ab3646fdf0a78/phoenix-core/src/main/java/org/apache/phoenix/monitoring/OverAllQueryMetrics.java#L86] > and > [stopResultsetWatch|https://github.com/apache/phoenix/blob/dcc88af8acc2ba8df10d2e9d498ab3646fdf0a78/phoenix-core/src/main/java/org/apache/phoenix/monitoring/OverAllQueryMetrics.java#L95]) > and so these metrics get 2X the value they should. Ideally we should change > the metrics only if the stopWatch was running before calling stopWatch.stop > or else we will count it multiple times. -- This message was sent by Atlassian Jira (v8.3.4#803005)
