Subject [jira] [Commented] (HBASE-13448) New Cell implementation with cached component offsets/lengths
Date Thu, 16 Apr 2015 15:40:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13448?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14498188#comment-14498188

stack commented on HBASE-13448:
-------------------------------

bq. The increase in GC is the young GC activity only ?

Likely. Lets try and avoid garbage though if we can; garbage == CPU. I'd be interested in
a patch that has metrics that show how often these parses are done getting a Cell out to a
client; perhaps the key and value lengths are parsed multiple times but say, the timestamp
or qualifier once only?
