Subject [jira] [Commented] (PHOENIX-5231) Configurable Stats Cache
Date Sat, 25 May 2019 22:38:00 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-5231?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16848295#comment-16848295
] 

Lars Hofhansl commented on PHOENIX-5231:
----------------------------------------

Also did a clean build (without patch).
{code:java}
phoenix$ jar -tf phoenix-client/target/phoenix-client-4.15.0-HBase-1.5-SNAPSHOT.jar | grep
GuidePostsCacheFactory

org/apache/phoenix/query/ITGuidePostsCacheFactory.class
org/apache/phoenix/query/GuidePostsCacheFactory.class
org/apache/phoenix/query/DefaultGuidePostsCacheFactory.class
{code}
So it's definitely not in the jar.

> Currently, the phoenix stats cache is per ConnectionQuerySerivce/ConnectionProfile, which
leads to duplicated cached entry (the guideposts) and waste resources if these separate connections
are querying the same underlying table. It would be good to be able to provide a configurable
stats cache as control the cache level so it could be per JVM.
