This is a backwards-compatibility option needed for rolling updates from Druid 30 and earlier. Flipping it to true means that the out-of-box experience will include new counters that have been added since then, such as CPU usage counters. Release note: When upgrading from Druid 30 or earlier, MSQ `query_controller` tasks can fail during a rolling update due to the addition of new counters that are not backwards compatible with these older versions. You can either retry any failed queries after the update completes; or you can set `includeAllCounters` to `false` in the query context for any MSQ jobs that need to run during the rolling update; or you can upgrade to Druid 31–35 first before upgrading to Druid 36. -- This is an automated message from the Apache Git Service.
