#
# Psude code for creating hash partitioned tables. 
# Algorithm:
# When a table is first created with a given shard count and 
# replication factor, generate a new collocationId. 
# If there already exists a collocation configuration with the 
# given shard count and replication factor, create placements 
# that are collocated with an existing table.
