NDBCluster partitioning by non unique column (no replies)

Hi All,

I want to partition Call Detail Record (CDR) ttable using non unique column "Calling_party" in NDB cluster. i see only key can be used for partitioning. i have generated auto-increment ID column. is it possible to make composite key {ID,Calling_party} and partition by this composite key ... ?

Thank You,
Bibek
