Hi,
I use it quite often, since I'm dealing with partitioning keys that have
high cardinality, ie, high number of different values. If your
cardinality is very high, but your spacing between values is not
uniform, HASH will balance your partitioned tables naturally. If your
spacing between

Hi!
I was reading up on declarative partitioning[1] and I'm not sure what could
be a possible application of Hash partitioning.
Is anyone actually using it? What are typical use cases? What benefits
does such a partitioning scheme provide?
On its face, it seems that it can only give you a numb
