I'm just curious. When dealing with JSON files that are 2.3Gb, what programming language do you use to parse it?

Ruby at the moment - my original (monolithic Rails) v0 version takes about 5 hours to process it and create database records with ActiveRecord - that's about 600,000 records - the microservices are using Oj for the JSON parsing and raw pg queries for database (so not a real comparison at the moment)
