askalt opened a new issue, #20293: URL: https://github.com/apache/datafusion/issues/20293
Type coercion and simplification applied to UDTF arguments may break some functions with specific arguments parsing logic. e.g. in our project we support UDTF that allows to specify index to scan a table: `scan_with(t, index=[ta, tb])`. Using `SessionContextProvider` as `ContextProvider` there is the error: ``` Schema error: No field named index. ``` It caused by the type coercion here: https://github.com/apache/datafusion/blob/4e2c0f1feaef2452323ada9c394ad943eb0b2805/datafusion/core/src/execution/session_state.rs#L1845-L1852 It would be nice to allow UDTF itself to handle arguments parsing. We could add a flag that will customize this behavior, allowing to pass args as is. -- This is an automated message from the Apache Git Service.
