Overview

Json-smart is a performance focused, JSON processor lib. Getting Start guide

Json-smart interfaces are almost the same that json-simple, So migration from json-simple to json-smart, is very easy. Migration Guide Available

Json-smart is one of the fastest java base Json API. See bench for more details. Benchmarks

json-smart overview

• Fast (it's at least twice faster) than the original json-simple See Benchmarks
• Use java Generics.
• Parser permissibility is highly customisable from permissive to strict.
• The json generator can generate compressed json data.
• Interfaces are the same, so json-simple projects can be easily port to json-smart.
• It uses maven build.
• Is available on maven central

Study case

I use this parser to process small json data stored in MySQL String records, limited to 255 chars.

In my case, every record contains simple JSon Object like:

{"first":"john", "last":"Doe"} # 30 chars long

I have rewritten the generator and the parser to also support smaller json data:

{first:john,last:Doe} # 21 chars long

So, I was able to reduce the json data size by 30%

Generation of simplified json string is only supported by the full json-smart version.
