> RowCacheTests were flaky and while investigating, I found that it does not
> store all the keys to disk.
> The reason is that we use OHCache and call hotKeyIterator on it. This is not
> guaranteed to return the number of keys we want. Here is the documentation
> from OHCache
> /**
> * Builds an iterator over the N most recently used keys returning
> deserialized objects.
> * You must call {@code close()} on the returned iterator.
> * <p>
> * Note: During a rehash, the implementation might return keys twice
> or not at all.

> CloseableIterator<K> hotKeyIterator(int n);
