MongoDB has evolved over the past seven years with three guiding design principles: developer productivity, horizontal scalability, and operational scalability. While MongoDB excels in horizontal scalability, improving developer and operations productivity is a more significant challenge. Recent improvements include document-level locking, pluggable storage, and automated management, which aim to enhance concurrency, flexibility, and ease of use for users. The new features have shown promising results, with a reported 10X speed increase in certain scenarios, and will be available in future versions of MongoDB, including version 2.8. These updates position MongoDB as a leader in the database market, making it more attractive to developers and operations teams alike.
