[jira] [Commented] (HBASE-25658) Basic benchmark to show the impact on performance for tracing

    [ https://issues.apache.org/jira/browse/HBASE-25658?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17312820#comment-17312820 ] 

Duo Zhang commented on HBASE-25658:
-----------------------------------

I set up a all-in-one jaeger receiver with downsampling 1.0, which means drop all the received tracing data, to minimum the effect on the receiver side.

I modified the tracing code a bit, where I removed the tracing on RegionScanner.next, because a scan rpc call from client side could lead to thousands of RegionScanner.next, so it is not a good idea to trace every RegionScanner.next call.

Still execute the same command, for HBASE-22120 with trace disabled

{noformat}
Write: 224758 row per second
[ Avg TPS/QPS]	205061	 row per second
[ Avg TPS/QPS]	242453	 row per second
[ Avg TPS/QPS]	226761	 row per second

Scan: 86981 row per second
[ Avg TPS/QPS]	86042	 row per second
[ Avg TPS/QPS]	86582	 row per second
[ Avg TPS/QPS]	88319	 row per second

Read: 2807 row per second
[ Avg TPS/QPS]	2770	 row per second
[ Avg TPS/QPS]	2776	 row per second
[ Avg TPS/QPS]	2876	 row per second
{noformat}

For HBASE-22120 with trace enabled and sampling ratio as 1.0, which means trace all, the result is

{noformat}
 -Dotel.traces.exporter=jaeger -Dotel.exporter.jaeger.endpoint=xxxxx:14250 -Dotel.metrics.exporter=none -Dotel.traces.sampler=parentbased_traceidratio -Dotel.traces.sampler.arg=1.0 -Dotel.resource.attributes=service.name=hbase
