["Michael Mior (JIRA)" <ji...@apache.org>]

Michael Mior updated CALCITE-1440:
----------------------------------
    Description: 
This can be implemented as a separate planner or in {{VolcanoPlanner}} itself. The planner should take multiple SQL statements as input and return a unified {{RelNode}} tree.

Example of above is as follows:

{{SELECT COL1, COL2 FROM TABLE WHERE COL3 > 10;}}
{{SELECT COL1, COL2 FROM TABLE WHERE COL4  = 'abc';}}

The above 2 statements have a common path and hence can provide a unified {{RelNode}} tree as follows:

{noformat}
 [Scan] -> [Project (COL1, COL2)] -> [Filter (COL4 = 'abc')] -> [Delta]
                    |
                    V
            [Filter (COL3 > 10)]
                    |
                    v
                 [Delta]
{noformat}
