Block locking for U/D on MDC when LOCKSIZE=BLOCKINSERT
Block locking is done for INSERTs on MDC tables when LOCKSIZE = BLOCKINSERT, which is a great benefit for memory usage, and allow to parallelize treatments for different dimensions.
However, this is unsufficient, because treatments do also Update/Delete, not only on dimensions, but on dimension + other predicates. This leads to lock escalation to table partition and deadlock when doing treatements in parallel.
