> Streaming Ingest API supports a concept of {{TransactionBatch}} where N transactions can be opened at once and the data in all of them will be written to the same delta_x_y directory where each transaction in the batch can be committed/aborted independently. The implementation relies on {{FSDataOutputStream.hflush()}} (called from OrcRecordUpdater}} which is available on HDFS but is often implemented as no-op in Blob store backed {{FileSystem}} objects.
> Need to add a check to {{HiveStreamingConnection()}} constructor to raise an error if {{builder.transactionBatchSize > 1}} and the target table/partitions are backed by something that doesn't support {{hflush()}}.
