[jira] [Commented] (HBASE-8769) Calculates the client write buffer size from the number of region

    [ https://issues.apache.org/jira/browse/HBASE-8769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13688115#comment-13688115 ] 

Lars Hofhansl commented on HBASE-8769:
--------------------------------------

The writer buffer is also per HTable.
Should we consider having the buffer capped per HConnection?

> The default size is ~2Mb. There are two issues:
> 1) It has not changed for a few years, while the memory available has increased
> 2) It's a fixed size, that does not take into account the number of region.
> I think we should have something like 100Kb per region, with a max at 6Mb, all this configurable of course.
> I plan to do this after HBASE-6295
