MongoDB 8.0 released: Major updates for Atlas and on-premises deployments

MongoDB has announced the general availability of version 8.0, marking a significant update for both MongoDB Atlas and on-premises deployments. This major release incorporates changes from previous Rapid Releases 7.1, 7.2, and 7.3. Among the key updates, MongoDB 8.0 aligns with the minimum operating system minor version support as defined by OS vendors.

The release introduces a refined Database Profiler, allowing configuration to log slow operations based on MongoDB's processing time, rather than total latency. Additionally, the $convert operator now facilitates conversions between string and binData values. Enhancements in $queryStats improve metrics tracking and reporting for change streams.

In terms of ranking operations, $denseRank and $rank now treat null and missing field values equivalently in sortBy operations. The update also supports moving collections between shards and unsharding collections in sharded clusters. MongoDB 8.0 includes various enhancements in sharding, replication, and other general improvements, offering a comprehensive upgrade for users.
