@alamb is there any documentation on what it means for DataFusion to "scan" specific rows within a row group? Does it actually read only those rows? I'd imagine that because of some mix of compression and limitations of byte range fetches to contiguous bytes for object stores you end up streaming entire row groups anyway. -- This is an automated message from the Apache Git Service.
