@loserwang1024 Thanks for the feedback! Here's my proposed fix: 1. No RPC proto change needed: The client already sends the expected projection indices. 2. Server-side alignment: In `createProjectionInfo()`, we split `selectedFieldPositions` into existing fields and missing fields. Then in `projectSingleBatch()`, we reconstruct the Arrow batch by copying existing vectors and generating all-NULL Arrow vectors for the missing columns at their correct target positions. -- This is an automated message from the Apache Git Service.
