JSON – probably everyone knows this lightweight data format used in almost all modern servers. It weights less, is more human-readable and in general is more dev-friendly than old-fashined, horrible xml. JSON is language-independend data format but parsing data and transforming it to e.g. Java objects costs us time and memory resources.
Several days ago Facebook announced big performance improvement in data handling in its Android app. It was connected with dropping JSON format and replacing it with FlatBuffers in almost entire app. Please check this article to get some basic knowledge about FlatBuffers and results of transition to it from JSON.
While the results are very promising, at the first glance the implementation isn’t too obvious. Also facebook didn’t say too much. That’s why in this post I’d like to show how we can start our work with FlatBuffers.
