Does this always coalesce many record batches into a single Arrow batch? Spark sometimes allows very large BHJs, with several GB of broadcast data. It might be better to use a single compressed Arrow stream containing multiple bounded-size record batches. We may also need to update DataFusion’s hash join implementation to support multiple `RecordBatch`es. -- This is an automated message from the Apache Git Service.
