Process large JSON files using steam based technologies

Most JSON data can be parsed in memory, but there are some edge cases when we have to process big data files - e.g. a database export or a data from a third party provider. For these scenarios the Jackson library provides stream-based read and write mechanisms to handle huge files efficiently.

But, there are some scenarios where parsing the entire data structure is not necessary and thus, low-level read and write methods from the Jackson library might be more efficient. In this post I will evaluate how some of those low-level methods can be used.
