> @dhatchayani What about the legacy store?
> For example, for the the non-dict-primitive column, in old store in
BloomFilter datamap, it stores the bytes and during query we will convert it to
bytes, but in the new store during query we will convert it to primitive
object, which will cause mismatch.
In the legacy store it is stored as bytes, in the new store it is stored as
primitive object, but while retrieving back from the query the query result is
unified to bytes only
