In streaming replication, is there such a concept as WAL shipping priority (now or in future releases), where you could set the priority of how fast effects of a transaction should make it to standby servers?
Let's say i'm going to execute a non-critical update that would add 2GB of WAL files. It would be great if the shipping of that 2GB would not delay smaller and more important WAL files that I want to send to the standby servers immediately.
Would this be possible now or in the future?
