Hi All, I have one table with data that can be grouped easily. I need to iterate over these groups, count their members and distribute them uniformly over the database nodes (physically). If I have three groups A, B, C of size (1, 1, 2) and two physical nodes - I want A,B to be on node no. 1 and C on the node no. 2. The question is quite simple. Is it possible?
