Currently, backfill sleeps for a minute in every iteration, which is extremely slow.

Can we have a little bit more explanation here that documents what you are changing? In addition the time.sleep(1) is very confusing why that is needed and if it can't be done differently. |

Currently, backfill sleeps for a minute in every iteration, which is extremely slow. The reason is that it waits synchronously until a heartbeat is necessary. Since the loop is otherwise fast, this results in waits of up to a minute between syncing. With this change, if we don't add sleep(1), the loop will be very fast and generate tons of logs. So I sleep each second to slow it down just a bit.
