## Jira Link [CALCITE-7574](https://issues.apache.org/jira/browse/CALCITE-7574) ## What Fix AssertionError when JDBC adapter uses window functions (RANK, ROW_NUMBER, etc.) in query. ## Why `ProjectToLogicalProjectAndWindowRule` has no convention restriction in its operand definition (trait is null, meaning match any convention). When `JdbcProjectRule` converts a `LogicalProject` with OVER to `JdbcProject` (JDBC convention), and then `ProjectToLogicalProjectAndWindowRule` fires on it, the JDBC traitSet propagates through `CalcRelSplitter` to `LogicalWindow.create()`. The resulting `LogicalWindow` inherits the JDBC convention but does not implement the `JdbcRel` interface, causing an AssertionError in `VolcanoPlanner.registerImpl`. -- This is an automated message from the Apache Git Service.
