supports atomic multiple reads and writes on a row".
Lars: Thanks for the feedback.
Yes, the RowProcessor implementation needs to exist on the RegionServer. In
our case, it's some predefined logic that we deployed on the server side.
We also thought about using coprocessor also but like you said it will need
to expose lots of details of HRegion. So it's not very easy.
I think you have really good points about the API. We should be very careful
about adding API because we can't take them back. The API should be as simple
as possible.
For our use case, this one is necessary because it allows execution of
multiple commands on the server. This is very important for the performance.
And I personally think the abstraction level is high enough to be a public API.
What do you think?
