[jira] [Commented] (HBASE-5349) Automagically tweak global memstore
and block cache sizes based on workload
[ https://issues.apache.org/jira/browse/HBASE-5349?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13204070#comment-13204070 ]
Zhihong Yu commented on HBASE-5349:
-----------------------------------
We currently don't maintain moving average of read/write requests per region server.
What should be an effective measure for determining read vs. write heavy workload ?

> Hypertable does a neat thing where it changes the size given to the CellCache (our MemStores) and Block Cache based on the workload. If you need an image, scroll down at the bottom of this link: http://www.hypertable.com/documentation/architecture/
> That'd be one less thing to configure.
