There are two tests, test_read_all and test_read_with_partition_row_limits, which asserts on every page as well
as at the end that there are no misses whatsoever. This is incorrect, because it is possible that on a given page, not all shards participate and thus there won't be a saved reader on every shard. On the subsequent page, a shard without a reader may produce a miss. This is fine. Refine the asserts, to check that we have only as much misses, as many
shards we have without readers on them.
