Hi Paul,
Your M0/M2/M5 Atlas cluster(s) will be automatically upgraded to MongoDB 8.0 in November 2024.
What’s in the update?
MongoDB 8.0 delivers unprecedented performance for your workloads compared with previous versions. While precise gains will vary from application to application, industry benchmarks and MongoDB’s internal testing indicate the following improvements vs MongoDB 7.0:
- 54% faster for bulk writes (Yahoo! Cloud Serving Benchmark, YCSB)
- 27% faster for reads (YCSB)
- 25% faster for 95/5 mix of reads & writes (YCSB)
- 18% faster according to Meta’s social graph benchmark (Linkbench)
- 60% faster for time series data (Timescale Time Series Benchmark Suite, TSBS)
What do I need to do?
MongoDB version 7.0-compatible drivers will continue to work with MongoDB version 8.0. To take advantage of new server features, upgrade your driver.
MongoDB version 8.0 introduces some compatibility changes. To determine if your workload may be impacted and if changes may be necessary, review the compatibility changes in 8.0.
Note: Most upgrades do not require any application changes. If you are concerned about compatibility, we recommend exploring MongoDB’s Stable API.
Not ready?
Control version upgrades and configure maintenance windows at your convenience when you upgrade to an M10 cluster. In addition to flexibility and control, M10 clusters come with premium features such as:
- Query Profiler and schema recommendations with Performance Advisor
- Expandable storage and auto-scaling options
- Unrestricted Atlas Search and Vector Search indexes and more
