MongoDB 3.0 is the newest and most significant release of the world’s fastest growing database. The version radically expands the use cases for MongoDB, allowing you to use it for the vast majority of all new applications. By improving performance by 7x - 10x, reducing storage needs by up to 80%, and lowering operations overhead by up to 95%, MongoDB 3.0 also dramatically increases your ability to deliver apps to market faster and more efficiently than ever before.

Download the white paper to learn about the latest features in 3.0:

  • Pluggable storage engines, including WiredTiger
  • Higher performance & efficiency
  • Simplified operations through Ops Manager
  • End-to-end auditing
  • Enhanced Query Language and Tools

몽고DB 3.2부터 wiredtiger 스토리지 엔진이 디폴트로 채용할 수도 있을 것이라는 얘기가 있다.

Support for the new WiredTiger storage engine will come later, most likely with the release of MongoDB 3.2, where it is expected to become the default storage engine for MongoDB.
