> 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.
> The PR 7975  implements hash partitioning.
