andygrove opened a new pull request, #4214: URL: https://github.com/apache/datafusion-comet/pull/4214
## Summary - When `NativeUtil.exportBatch` detects columns with mismatched row counts, the error message now includes each column's index, row count, and vector class name - Previously the message only showed the distinct row counts (e.g., `[ArrayBuffer(8192, 0)]`), making it hard to identify which column was problematic - The new message format is: `col[0]=8192 (CometDecodedVector), col[1]=8192 (CometDecodedVector), col[2]=0 (CometPlainVector)` ## Context This improves diagnostics for #4211 where `native_iceberg_compat` scans at scale hit this error. Knowing the column index and vector type will help identify the root cause. ## Test plan - [ ] Existing tests pass (no behavioral change for valid batches) 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
