Subject [jira] [Commented] (HBASE-5792) HLog Performance Evaluation Tool
Date Sun, 15 Apr 2012 21:25:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5792?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13254436#comment-13254436

Zhihong Yu commented on HBASE-5792:
-----------------------------------

I wonder if it makes sense to persist benchmark results to HBase.
That may show us some trend w.r.t. HLog performance.

> to be able to check easily the HLog performance.
