How to open and read LZMA file in-memory

Question

I have a giant file, let\'s call it one-csv-file.xz. It is an XZ-compressed CSV file.

How can I open and parse through the file without first decomp

Answer 1

You can decompress incrementally. See Compression using the LZMA Algorithm. You create an LZMADecompressor object, and then use the decompress method with successive chunks of the compressed data to get successive chunks of the uncompressed data.
