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}
