Hi, MongoDB & Rockset product teams are interested in your feedback on this new capability for external real-time indexing on MongoDB, that is currently in private beta. Looking for your comments, applicable use cases and also users who may be interested in early access.
This is a tech preview of the MongoDB integration with Rockset which supports millisecond-latency SQL queries in real-time. Rockset builds fully mutable external indexes on any fields, including deeply nested fields in JSON documents, from your MongoDB collections. It uses your MongoDB Change Streams to stay in sync with inserts, updates and deletes, so that new data is queryable in ~2 seconds. By default, Change Streams only return the delta of fields during the update operation so this means there is minimal impact to your production database performance.
