I am not sure this will work for SQL JDO; probably it will just get all of them
and return limited number of rows.
2) Due to absence of offset, it's really a semi-useless parameter; I don't
see it used.

> While testing some queries I noticed that getPartitions can be very slow
> (which happens e.g. in non-strict mode with no partition column filter); with
> a table with many partitions it can take 10-12s easily. SQL perf path can
> also be used for this path.
