Oh I forget the file format. Just a question, in this case, seems the data is stil mmaped, but Stream will need to parse the whole file schema, and mmap the area to arrow batches. `stream` will spend more time mapping, but seems that they're all memory mapping. When user want to loading all data to memory-mapped RecordBatches, how could this benifit the reading time? -- This is an automated message from the Apache Git Service.
