Index manager
Review MongoDB indexes in Spanna and use them to reason about query performance.
› /docs/index-manager
Indexes affect query speed, write overhead, and storage cost.
Use the Indexes tab to
- list current indexes
- inspect indexed fields
- verify whether important queries are covered
- refresh index state after changes
When to review indexes
- a query feels slow
- explain shows a collection scan
- a new feature introduces new filters or sorts
Common checks
- is the right field indexed
- is compound key order sensible
- are old indexes still needed
