Andrew Purtell commented on HBASE-21034:
----------------------------------------
I'm aiming for 1.5.x -> 2.2.x. Will update the doc.
The order in which we must make commits is master -> branch-2 -> branch-1.
Nothing can be in branch-1 that is not in branch-2. Everything else is
situational.

> 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.
