I wrote an article for Baeldung on various ways of reducing the size of JSON in our Java applications. Java applications often use JSON as a common format for sending and receiving data. Moreover, it's used as a serialization protocol for storing data. With smaller JSON data sizes, our applications become cheaper and faster.
I wrote an article for Baeldung on how to use gzip and gunzip for compressing and uncompressing files from the Linux command line. It included using gzip with tar and speeding up archiving with pigz, a parallel implementation of gzip.
