    Description

      JDK1.8+ is recommended in the Community document.

       This issue is to switch JVM settings default from MaxPermSize to MaxMetaspaceSize.

       

      Problem discovery

      If you use jdk1.8 and setting MaxPermSize, the query will slow down when non-heap memory is not recovered timely. The threshold value is about 1GB. The average query time may change from 500ms to 1000ms, or more.
