Amazon DocumentDB (with MongoDB compatibility) adds $dateFromString and executionStats capabilities
Amazon DocumentDB (with MongoDB compatibility) is a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads. Amazon DocumentDB makes it easy and intuitive to store, query, and index JSON data.
Amazon DocumentDB continues to increase compatibility with MongoDB. Today, Amazon DocumentDB added support for two new capabilities. First, $dateFromString, an additional aggregation pipeline operator has been added that allows you to compose powerful aggregations over your documents. Second, Amazon DocumentDB now supports executionStats mode for explain, which provides detailed execution times for stages within query plans. The supported MongoDB APIs and aggregation pipeline capabilities for Amazon DocumentDB can be found here.
To use the new capabilities, you can create a new Amazon DocumentDB cluster with just a few clicks in the Amazon DocumentDB Management Console or you can upgrade your existing cluster.
