jorgecarleitao opened a new issue #533: URL: https://github.com/apache/arrow-datafusion/issues/533
As a user of DataFusion, I would like to be able to install custom parsing rules of SQL to DataFusion, so that I can plan custom nodes from SQL. This would allow me to extend datafusions' core capabilities beyond its supported SQL. Examples: * `OPTIMIZE`, `VACUUM` * `select * from t version as of n` (delta lake) I would like to support 2 main cases: * Parse entire SQL statements (e.g. `select * from t version as of n`) into a logical node * Parse single SQL expressions (e.g. `my_custom_expr` in `select my_custom_expr(t) from table1`) a custom logical expression -- This is an automated message from the Apache Git Service.
