What do you Mean, Backwards Compatibility?

YOW! 2013 Melbourne

The Java driver for MongoDB has been around almost as long as the NoSQL database itself. It was designed without some of the modern Java features we now take for granted, and the API might be easier with features like lambdas.

The existing Java driver is extensively used, which leads to a tricky question: how do you create a new API that uses modern development patterns whilst retaining backwards compatibility? Your users are fundamental to the success of your business, you do not want to alienate them, break their systems or make it hard for them to migrate to the New World Order.

In this presentation Trisha will share some of the pain experienced and solutions tried while creating a new Java driver for MongoDB.
