It also takes care of setting up publications, replication slots and the initial sync.

No guarantees on latency as this depends on the hardware.

Check the load test

The date fields are actually timestamps having microsecond accuracy. Maybe this was not clear in the docs.

kuvasz-streamer batches updates in a single timed transaction (1 second for example). This is independent of the source transaction.

I have seen a significant increase in performance with this feature.
