That is a rather small batch size. I don't know how much profiling or focus we've had on sizes that small. You might try something larger, like 32k. I would expect the scanner to be slightly slower than ParquetFileReader directly but not 2x. If you don't support any multithreading, not even I/O readahead, then what advantages are you hoping to gain by using the scanner instead of ParquetFileReader? -- This is an automated message from the Apache Git Service.
