    Per-Shard Change Stream and Triggers to improve scalable/performance/resilience

    In our geo-sharded cluster, we use Change Streams and Atlas Triggers. Most of our pipelines include a match for the shard key - so we can process the data in the same region where the data resides. However, due to the design of change streams wit...

    Identification of unused/less used collections

    As a DBA I'd like to identify unused collections so that I can remove them to optimize performance. As of now there doesn’t seem to be a direct way. One option could be to settup auditing or using logging (e.g. set the slow op timer to 0 so we log...

    Disallow new connections that don't specify an appName field

    Currently as a DBA it's sometimes hard to identify which service is causing load on a shared cluster/database. Some people connect for adhoc workloads but don't specify an appName making it hard to track back to the owner. It would be useful to re...

    Generative AI and Smart Automation should be a key priority. MongoDB Atlas could significantly improve developer productivity by introducing AI-assisted query optimization that doesn’t just flag inefficient queries, but actively rewrites them into optimized alternatives. Automated index recommendations based on real workload telemetry would help teams make better performance decisions without deep manual analysis. Additionally, bot-assisted support workflows could speed up issue resolution by guiding users through diagnostics and common fixes more efficiently. Together, these capabilities would provide strong competitive differentiation while improving operational efficiency for both developers and platform teams.

    What problem are you trying to solve? Focus on the what and why of the need you have, not the how you'd like it solved. Teams struggle to proactively identify and fix performance issues in MongoDB workloads. Query inefficiencies, missing or s...
