My current use-case is in the context of a PoC where I generate testdata with configurable data volumes in a generic but deterministic way (a non real-life scenario). I know that HANA provides internal partitioning out of the box (e.g., the PARTITION BY HASH (a) PARTITIONS 12 option for table creation). Is there a way to explicitly apply partition pruning in a select statement, e.g. to enable for parallel reading with an external ETL Tool? In Oracle I would use a PARTITION clause to explicitly prune a query to a certain hash partition.
I admit that this might not be a common use-case and this may not be needed in many real-life scenarios. But in the past explicite hashing/pruning/parallelization came handy in some performance critical ETL situations.
Many thanks,
