> It is often difficult to find an appropriate partition key in the existing
> data. Hash partitioning can easily solve this problem
> When hash.partition.fields is specified and partition.fields contains
> _hoodie_hash_partition, a column named _hoodie_hash_partition will be added
> in this table as one of the partition key.
> If predicates of hash.partition.fields appear in the query statement, the
> _hoodie_hash_partition = X predicate will be automatically added to the query
> statement for partition pruning.
