Padma Penumarthy updated DRILL-5287: ------------------------------------ Labels: doc-impacting ready-to-commit (was: ready-to-commit) > Provide option to skip updates of ephemeral state changes in Zookeeper > ---------------------------------------------------------------------- > > Key: DRILL-5287 > URL: https://issues.apache.org/jira/browse/DRILL-5287 > Project: Apache Drill > Issue Type: Bug > Affects Versions: 1.9.0 > Reporter: Padma Penumarthy > Assignee: Padma Penumarthy > Labels: doc-impacting, ready-to-commit > Fix For: 1.10.0 > > > We put transient profiles in zookeeper and update state as query progresses > and changes states. It is observed that this adds latency of ~45msec for each > update in the query execution path. This gets even worse when high number of > concurrent queries are in progress. For concurrency=100, the average query > response time even for short queries is 8 sec vs 0.2 sec with these updates > disabled. For short lived queries in a high-throughput scenario, it is of no > value to update state changes in zookeeper. We need an option to disable > these updates for short running operational queries. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
