Dear Community, I'm working on integration with Apache Apex and Apache Calcite (underlying Apache Jira is: APEXMALHAR-1818).
I have a question related to conversion from SQL to RelNode Tree. Is it possible that VolcanoPlanner can 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'; Above 2 statements has a common path and hence can provide an unified RelNode tree as follows: [Scan] -> [Project (COL1, COL2)] -> [Filter (COL4 = 'abc')] -> [Delta] | V [Filter (COL3 > 10)] | v [Delta] Thanks, Chinmay.
