> [https://github.com/apache/kafka/pull/10650] showed a case where active
> segment was absent when Log layer segments were iterated. We should
> investigate Log layer code to see if we can change Log layer segment map
> mutations to avoid absence of active segment at any given point. For example,
> if we are clearing all segments and creating a new one, maybe we can reverse
> the order to create a new segment first and then clear the old ones later.
