Is there any way to batch conditional mutations

[Cosmin Lehene <cl...@gmail.com>]

Hi, 

I'm trying to figure out if I can do any of the following:

* checkAndMutate with more than one condition (e.g. OR)

* have multiple checkAndMutate operations batched in order to benefit from the rowlock.

Thank you,

Cosmin

Doesn't look like it. The CheckAndMutateBuilder implementation only allows
setting one comparator and one value. The CompareOperator is a fixed-set
enum (doesn't have an OR).

Submitted batches of checkAndMutate seem to be grouped up fine by region
but when they get to the server they are applied one at a time getting
rowlock per 'check' (It looks like a bunch of Mutations can go in under
this single check but not multiple checks after acquiring row locks.

Its slow for you Cosmin?
