Chao Chu commented on HBASE-8458:
---------------------------------

I am also interested in this issue. Having gone through all the comments above, it looks like we don't have a solution to achieve an equivalent of batch checkAndPut?

> The use case is that the user has multiple threads loading hundreds of keys into a hbase table. Occasionally there are collisions in the keys being uploaded by different threads. So for correctness, it is required to do checkAndPut() instead of a put(). However, doing a checkAndPut() rpc for every key update is non optimal. It would be good to have a batch version of checkAndPut() similar to batch put(). The client can partition the keys on region boundaries.
> The jira is NOT looking for any type of cross-row locking or multi-row atomicity with checkAndPut()
> Batch version of checkAndDelete() is a similar requirement.
