In the latest release of MongoDB, developers and DBAs can leverage a richer query language, enhanced tools such as mongoimport and mongostat, which are now multi-threaded processes in Go, allowing faster operations and smaller binaries. The explain() method has been significantly enhanced to enable DBAs to review query plans without having to run the queries first, and provides detailed statistics on all query plans considered by the optimizer. MongoDB 3.0 also introduces big polygon geospatial support with $intersects and $within operators, allowing execution of queries over geographic areas extending across multiple hemispheres and areas that exceed 50% of the earth's surface. Additionally, the aggregation pipeline offers a new $dateToString operator that simplifies report generation and grouping data by time interval, while enhanced logging provides greater control over the granularity of log messages and specific functional areas of the server to more precisely investigate issues. The release also enables deploying geo-distributed, datacenter-aware applications with up to 50 members per replica set, delivering higher fault tolerance and reduced read latency for highly distributed consumers.
