Source-anchored research for Compass Performance Insights. Run status: COMPLETED.
These notes link each claim to its source. Some citations identify archived research reports that are no longer hosted on this site. A published reference means the content is available; it does not certify independent review or accuracy.Read the editorial policy and follow the sources before relying on a claim.
How it works
- The documented schema prompts cover excessive collections, large arrays, oversized documents, and excessive indexes; another prompt suggests embedding related data when $lookup is used. (low confidence) [source]
- Review suggestions against actual application needs before changing a schema; an advised index should support frequently used queries. MongoDB recommends applying the guidance early because production schema changes can be harder. (low confidence) [source]
- A query or aggregation executed without an index triggers guidance to add a supporting index. (low confidence) [source]
- Other documented triggers include excessive collections, array elements, document size, or indexes; the page supplies no numeric detection thresholds. (low confidence) [source]
Comparisons and alternatives
- TECHBETA labels explain-plan visualization as Performance Insights; this terminology differs from MongoDB’s dedicated recommendation-feature documentation. (medium confidence) [source]
Facts and statements
- Compass Performance Insights presents schema and query improvement suggestions within the GUI; OVHcloud also lists performance insights among Compass's developer tools. (high confidence) [source]
- Compass 1.39.0, released July 14, 2023, enabled proactive performance insights by default. (high confidence) [source]
- Documented query prompts recommend indexing unindexed operations and considering Atlas Search for $text or $regex queries; 2023 release notes also record these insight types. (high confidence) [source]
- MongoDB describes performance insights as generic: their messages do not use schema-specific database or collection names. (low confidence) [source]
- MongoDB's COMPASS-10146 issue was resolved December 22, 2025 with fix version 1.49.0. It records re-enabling the unindexed-query proactive-insights entry point after adding assistant context and read-only database tool support. (low confidence) [source]
- An InfluxDB feature proposal opened September 21, 2026 cites Compass schema suggestions as prior art alongside Atlas and Ops/Cloud Manager. This is an external proposal's assessment, not an independent benchmark of Compass. (low confidence) [source]
- Compass provides graphical database exploration with performance-insight capabilities. (medium confidence) [source]
- Documented prompts suggest embedding for $lookup and considering Atlas Search for $text or $regex. (low confidence) [source]
- The documented insights can direct users to the Compass Intelligent Assistant for additional help. (low confidence) (verified as of 2026-10-14) [source]
