Here's a dumb question about log-structured systems like this: does this system work nicely with backfills? Suppose you start logging events with Waltz and you want to migrate an existing system's data into the same log. Or something goes wrong and oncall needs to manually insert old events. Does Waltz have capabilities to backfill events into the historical log or reassign transaction IDs?

This might not be needed if this is strictly used for FIFO event consumption, but I guess I was thinking of trying to make a system like this support time-sliced queries.
