Enis Soztutar commented on HBASE-11274:
---------------------------------------
I like this. I was thinking expanding checkAndXXX() interfaces to accept a list
of Conditions as well. Should we do more-generic single-row transactions?
An example of an in-row transaction:
- If Column A == 5, set Column B = Column C + Column D
Our RowProcessor is kind-of doing that, but it is not easily consumable from
client side right now. [~lhofhansl] FYI.
> More general single-row Condition Mutation

> Currently, the checkAndDelete and checkAndPut interface only support atomic
> mutation with single condition. But in actual apps, we need more general
> condition-mutation that support multi conditions and logical expression with
> those conditions.
> For example, to support the following sql
> {quote}
> insert row where (column A == 'X' and column B == 'Y') or (column C == 'z')
> {quote}
> Suggestions are welcomed.
