-------------------------------------

             Summary: Default hbase.client.scanner.max.result.size
                 Key: HBASE-12976
                 URL: https://issues.apache.org/jira/browse/HBASE-12976
             Project: HBase
          Issue Type: Bug
            Reporter: Lars Hofhansl


Setting scanner caching is somewhat of a black art. It's hard to estimate ahead of time how
large the result set will be.

I propose we hbase.client.scanner.max.result.size to 2mb. That is good compromise between
performance and buffer usage on typical networks (avoiding OOMs when the caching was chosen
too high).

To an HTable client this is completely transparent.
