Subject [jira] [Commented] (HBASE-13707) CellCounter uses to many counters
Date Mon, 18 May 2015 20:57:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13707?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14549211#comment-14549211

Jean-Marc Spaggiari commented on HBASE-13707:

Exactly. Very good for very wide tables with only few rows. You can still increase the maximum
number of counters but it become crazy quickly.

            context.getCounter("QL_VERSIONS", currentRowKey + separator +

It creates one counter per row using the rowkey as the name to give you how many cells and
versions there is per row. It's still useful in some cases, but generally speaking it creates
to many counters...

I think we should "simply" add an option to not count per row, but only per table, so just
add a parameter and an if before this line.

> CellCounters creates a counter per row... So it quickly becomes to many.
> We should provide an option to drop the statistic per rows and count only cells overall
for the table.
