Scans should not pollute the cache with cold data, in general. In the case of the batchlog table, there is another reason to bypass the cache: this table can have a lot of partition tombstones, which currently are not purged from the cache. So in certain cases, using the cache can make batch replay very slow, because it has to scan past tombstones of already replayed batches.
