We generally recommend explicit index creation for application-based control of indexes as Spring Data cannot automatically create indexes for collections that were recreated while the application was running.
`IndexResolver` provides an abstraction for programmatic index definition creation if you want to make use of `@Indexed` annotations such as `@GeoSpatialIndexed`, `@TextIndexed`, `@CompoundIndex`.
`IndexResolver` provides an abstraction for programmatic index definition creation if you want to make use of `@Indexed` annotations such as `@GeoSpatialIndexed`, `@TextIndexed`, `@CompoundIndex` and `@WildcardIndexed`.
You can use index definitions with `IndexOperations` to create indexes.
A good point in time for index creation is on application startup, specifically after the application context was refreshed, triggered by observing `ContextRefreshedEvent`.
This event guarantees that the context is fully initialized.
Note that at this time other components, especially bean factories might have access to the MongoDB database.
[WARNING]
===
`Map` like structures, unless annotated with `@WildcardIndexed`, are skipped by the `IndexResolver` because the _map key_, which cannot be resolved from static metadata, needs to be part of the index definition.
