Subject [jira] [Commented] (HBASE-6925) Change socket write size from 8K to 64K for HBaseServer
Date Thu, 01 Nov 2012 13:23:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6925?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13488683#comment-13488683

Karthik Ranganathan commented on HBASE-6925:

Where is the chunking (that JIRA had a lot of stuff to parse)? Right now, in 89-fb, the client's
nio send buffers are at 128K, and the input stream that reads from the nio buffer is only
8K. This change is on the server side. I would hypothesize that scan (which return a lot of
data) will benefit from this.

> Creating a JIRA for this, but the change is trivial: change NIO_BUFFER_LIMIT from 8K
to 64K in HBaseServer. This seems to increase scan throughput.
