Hello -
Running Percona Server 5.5.38-35.2-log, and looking at the pt-query-digest report from our slow log (set to 2 seconds). Many of the queries reported are simple index-supported SELECTS, but they are showing the majority of the time as “queue wait”. I’ve been researching, but it is not clear to me what that is counting. Can someone shed some light on what that means? Here is an example
Query 1: 0.03 QPS, 0.08x concurrency, ID 0x2A76B7CFBB6C34B4 at byte 3204805
This item is included in the report because it matches --limit.
