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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
