> Pulsar connector didn't use the consuming position for the checkpoint. They just commit the position to Pulsar after the checkpoint and start consuming from it directly.
> This causes the test could be failed in some situations. The start cursor would be reset to the wrong position which causes the results didn't match the desired records.
