One of the best ways to handle large files is to read them in smaller chunks rather than loading the entire file into memory. Python provides ...

A three part case study ( since extended to 5 parts) in reading a big (21GB) text file using C, Python, PYSPARK, Spark-Scala and Athena/Glue.

Reading a large file using the above method is problematic and will unnecessarily overflow the memory since it attempts to load the WHOLE content at once into ...
