On-the-fly Schema Migration Tool for MongoDB ##Overview Currently, applications have to hand-roll their own schema migration infrastructure or use some third-party tool It is difficult to migrate TBs of data without downtime (unacceptable from SLA stand-point!). This is where Midas fills the gap.
It intercepts responses at MongoDB Protocol level and upgrades or downgrades document schema in-transit. As Midas works at protocol level, it is agnostic of Language specific MongoDB drivers (Ruby, Python, C# and Java drivers) and their versions within those languages
Further, Midas is Agnostic of the MongoDB configurations like Standalone, Replica Sets, Sharded environments.

We are using Gradle 1.8 for our builds. Please do not checkin Eclipse or Intellij or any IDE specific files.
For Idea or Eclipse they can be generated using

Note: Eclipse IDE might show the following error for groovy files: "Error compiling Groovy project. Either the Groovy-JDT patch is not installed or JavaBuilder is not being used." This is because groovy plugin for eclipse needs JavaBuilder but doesn't understand ScalaBuilder.
