Hello,
We have a requirement to determine whether a PUT will create a new row or
update an existing one. I looked at using preBatchMutate in a co-processor and
have the code below.
Few things I need to ask:
1) Is there a more efficient way of doing this?
2) Will region.getClosestRowBefore() add

For #2, region.getClosestRowBefore() calls store.getRowKeyAtOrBefore(row)
Take a look at HStore#getRowKeyAtOrBefore() (around line 1619):
IteratorStoreFile sfIterator = this.storeEngine
.getStoreFileManager()
.getCandidateFilesForRowKeyBefore(state.getTargetKey());
