MongoDB Database Reaches 2.0

The MongoDB team have released version 2.0 of the MongoDB document-oriented database. This release introduces a compact command for compacting a single collection and its indexes, and the default stack size has been reduced. MongoDB users can now use authentication with sharded clusters. Replica data set members can be tagged to indicate their locations, and these tags can then be used to design custom written rules across specified servers, racks, or other architecture choices. New geospatial features have also been introduced, including support for indexing on documents which have multiple location objects, and support for polygonal $within queries for simple polygon shapes. More information on the new features, is available at the Release Notes.
