> Currently, each log.append() will add at most 1 index entry, even when the appended data is larger than log.index.interval.bytes. One potential issue is that if a follower restarts after being down for a long time, it may fetch data much bigger than log.index.interval.bytes at a time. This means that fewer index entries are created, which can increase the fetch time from the consumers.
