json-smart-v2

Json-smart development started in 2010, when SQL servers did not support native JSON fields, NoSQL databases were slowly emerging, and all the existing JSON APIs were bogus. I wrote lots of tests to benchmark and compare JSON java parsers.

I never liked SQL databases because it's almost impossible to update a data model without impacting the production platform. Adding a column is a terrible operation.

So I started json-smart. All non-indexed data in my datastores were stored in a column as a serialized JSON message. To fit MySQL varchar(255) fields, I tried to make my JSON as small as possible, so json-smart is optimized to produce small JSON-like Strings.

Now times have changed: most of the JSON APIs are now stable, and I'm now using document-oriented databases and JSON-native SQL types.

So I do not use my json-smart anymore. I had fun with this project. If you want to apply some change on json-smart create a pull request with lots of JUnit tests.
