> @ildipo where does substrait uses dataset? (This is slightly surprising to me because I thought substrait code mostly just read in substrait plan protobuf and turn into an Acero declaration) @icexelloss the `scan` and `write` nodes are provided by datasets. You can use `source` (e.g. an in-memory source) with plain Acero but if you want to scan files you need datasets. Substrait's `ReadRel` when `LocalFiles` will use a `scan` node. -- This is an automated message from the Apache Git Service.
