 int ordinalBase,
 SharedSessionContractImplementor session,
 DecompositionContext decompositionContext,
 Consumer<FlushOperation> operationConsumer)

Description copied from interface: CollectionPersister

Removes the collection:

Queued collection operations often have no SQL work of their own, but still need flush-time lifecycle cleanup after the plan reaches the action.
