backkem commented on issue #970: URL: https://github.com/apache/arrow-datafusion/issues/970#issuecomment-1896646767
I put together a POC based on the concept above ([example](https://github.com/backkem/datafusion-federation/blob/master/examples/examples/sqlite.rs)). It's by no means complete but helps determine viability. One annoying thing I faced: when replacing a sub-plan containing multiple `TableScan`s with one opaque 'virtual' `TableScan`, the remainder of the original plan still contains references to the original tables. The outer plan will likely have to be re-written entirely to overcome that. -- This is an automated message from the Apache Git Service.
