Subject [jira] [Commented] (PHOENIX-5231) Configurable Stats Cache
Date Sat, 25 May 2019 22:30:00 GMT


Lars Hofhansl commented on PHOENIX-5231:

Thanks [~dbwong], I didn't mean to seem annoyed above. Apologies.

This was with 4.x-HBase-1.5.

In my case I took the produced phoenix-4.15.0-HBase-1.5-SNAPSHOT.tar.gz, unpacked it as usually,
put the -server jar into the HBase lib directory, and then ran sqlline in phoenix/bin.

The -client jar inside the tar.gz does not contain META-INF/services/org.apache.phoenix.query.GuidePostsCacheFactory
(verified with jar -tf) unless I apply the quickfix-v2.

> 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.
