Transactional consistency
Data Replication for VSAM preserves transactional consistency between your source and target data sets by maintaining the sequence of changes to a record.
In parallel apply processing, transactions can be applied to the target in a different order than they were applied at the source, provided that any dependent transactions are applied first.
Because low latency is also a high priority in replication, your subscription design must optimize the tradeoff between latency and maintaining precise order.
