Checkpoints happen in the following cases: on timeout, but padding one of the persistent data region by 0.75 (many dirty pages) if segments without a breakpoint are greater than 0.25% (i.e. 3 out of 10).
If all 10 segments are filled, then it will be expected (wait) for the first of the segments to go to the archive. Transferring the segment to the archive is possible only after the checkpoint, since we have accurately written the data to disk. The archive is an optimization that can be disabled. Segments may be useful for rebalancing instead of a full data transfer, only the difference will be transferred. In theory, exceeding the maximum is possible, but already lower than it was before.
