Looking at the CAS unit tests [1], if one does a CAS UPDATE to create a ROW:
UPDATE test SET v1 = 2, v2 = 'foo' WHERE k = 0 IF NOT EXISTS
there isn't a CAS DELETE FROM that only uses the partition key. You can
do this to delete the row using CAS:
DELETE FROM test WHERE k = 0 IF v1 = null
But if I want to delete it regardless of v1, then this doesn't work:
DELETE FROM test WHERE k = 0 IF EXISTS
So one is left to
DELETE FROM test WHERE k = 0
How does this non-CAS DELETE mix with a CAS UPDATE for the same
partition key? Will they properly not step over each other?
Thanks,
Blair
