Limiting Memory Usage #35
Description
Currently, csv2xlsx parallelizes and grabs as much memory as it can. It would be great if we could restrict how much memory it will use, maximum, with a parameter. Something like --max-memory 16GB to limit to 16 gigabytes.
We use csv2xlsx to sometimes convert CSVs with a thousand columns and hundreds of thousands of rows, and it will take all 256 GB of RAM on the server. While we could resource restrict at the OS level, it would be really nice to have a command-line option. I looked through the source and saw the dependency on github.com/tealeg/xlsx/v3 v3.3.12, and Go isn't my forte, so I'm not sure how feasible this might be.
Thanks for your efforts on this fantastic tool.
