Data Load from Asterix

Ok, I guess once the hash partitioning is done, you can support both scenarios:
s1.  asterixdb partitioning is the same as the pregelix cluster -- in this case, you avoid partitioning.
s2.  asterixdb partitioning is different from pregelix -- in this case, you do hash partitioning.

Maybe you can test Pregelix for both scenarios:
1. using the old store.properties to test s2
2. using the your new stores.properties file to test s1.
