  • How to sort large text data in Python

    We currently have a large file (that's over 100 million lines of tab separated values, which is about 1.5 GB in size). Does anyone know of a fast way we can sort this file through one of the fields. We already tried Hive but that was too slow. Would Python be able to do this?
