[jira] [Comment Edited] (HBASE-21034) Add new throttle type:
read/write capacity unit
[ https://issues.apache.org/jira/browse/HBASE-21034?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16745427#comment-16745427 ]

-------------------------------------------------------------------
branch-2.1 is tracking a dot release though. Branch-1 is different cause it's tracking 1.X (1.6?), but I'd assume branch-2.1 is 2.1.X, so it's bug fixes only?
Ditto for branch-2.0 (2.0.X). 2.2 would be a vehicle for new features on 2.X line, at least that was my impression.

> Add new throttle type: read/write capacity unit like DynamoDB.
> One read capacity unit represents that read up to 1K data per time unit. If data size is more than 1K, then consume additional read capacity units.
> One write capacity unit represents that one write for an item up to 1 KB in size per time unit. If data size is more than 1K, then consume additional write capacity units.
> For example, 100 read capacity units per second means that, HBase user can read 100 times for 1K data in every second, or 50 times for 2K data in every second and so on.
