> When writing to memory, does the additional BufWriter have an appreciable performance cost? That would be my only concern, otherwise this seems like a substantial win 👍 Yea, on the benchmark of writing to in-memory writer, the additional BufWriter is slower. However I think file writer is preferred as this is for Parquet writer so I assume the practice usage is file-based instead of in-memory which is basically for test purpose. -- This is an automated message from the Apache Git Service.
