Josh Elser created HBASE-25278: ---------------------------------- Summary: Add option to toggle CACHE_BLOCKS in count.rb Key: HBASE-25278 URL: https://issues.apache.org/jira/browse/HBASE-25278 Project: HBase Issue Type: New Feature Components: shell Reporter: Josh Elser Assignee: Josh Elser Fix For: 3.0.0-alpha-1, 2.4.0
A trick I've found myself doing a couple of times (hat-tip to [~psomogyi]) is to edit table.rb so that the `count` shell command will not instruct RegionServers to not cache any data blocks. This is a quick+dirty way to force a table to be loaded into block cache (i.e. for performance testing). We can easily add another option to avoid having to edit the ruby files. -- This message was sent by Atlassian Jira (v8.3.4#803005)
