@lidavidm Thanks! How can I memory-map a Parquet file? I want to gain 'zero copy' from a directory database(pyarrow). In Microsoft Power BI, We must read all dataset to memory and process it. The Memory will be the bottleneck. Should I use uncompressed feather( memory map, file named *.arrow) file in directory, to gain 'zero copy' benefits? -- This is an automated message from the Apache Git Service.
