[jira] [Created] (IGNITE-18901) Sql. ColocationGroup refactoring

Konstantin Orlov created IGNITE-18901:
-----------------------------------------

             Summary: Sql. ColocationGroup refactoring
                 Key: IGNITE-18901
                 URL: https://issues.apache.org/jira/browse/IGNITE-18901
             Project: Ignite
          Issue Type: Improvement
          Components: sql
            Reporter: Konstantin Orlov


Currently, ColocationGroup has two-dimensional list of assignments, where first dimension is partition id, and the second is list of nodes handling this partition. Keeping in mind that placement driver will told us which partition should be handled by which node, having two dimensions seems like unreasonably complex design. Besides, there is actually no place that expects to see all possible replicas in second dimension.

The second dimension can be safely eliminated in sake of code simplicity.
