[GitHub] [arrow] westonpace commented on issue #35371: How to read an Arrow IPC with multiple record batches in C#

   `RecordBatch.Builder.Append(RecordBatch)` doesn't work how I think you are expecting.  Instead of combining the rows from the two batches (making a longer record batch) it combines the columns from the two batches (making a wider record batch).
   
   There is no class that does the concatenating behavior you are describing today though it seems a reasonable enhancement request.
