Work on HBASE-26648 started by Nick Dimiduk. -------------------------------------------- > Improve fidelity of RegionLocator spans > --------------------------------------- > > Key: HBASE-26648 > URL: https://issues.apache.org/jira/browse/HBASE-26648 > Project: HBase > Issue Type: Sub-task > Components: tracing > Reporter: Nick Dimiduk > Assignee: Nick Dimiduk > Priority: Major > > While backporting HBASE-26474 to branch-2, I realized that the nuance of > tracing of region locator calls is lacking. In the current implementation, > all calls to the region locator produce {{SpanKind.CLIENT}} spans. This is > correct only for the code path where the client reaches out to a remote host > to populate cache locations. This doesn't happen every time. > Instead, the top-level span should be {{SpanKind.INTERNAL}} and only when a > region location must be requested remotely should we create a child span with > {{SpanKind.CLIENT}}. -- This message was sent by Atlassian Jira (v8.20.1#820001)
