# Test covers the different NDB specific partitioning schemes
# (specified as a part of NDB_TABLE option) and checks if
# the partition information from I_S is as expected
#
# Note: The actual partitioning of data is not checked in
# this test. The focus is more on creation of the partitions
# and checking that I_S (DD) and NDB Dictionary
# match in terms of their parition metadata.
