Indexes and query optimization
Indexes in MongoDB are specialized data structures that play a crucial role in enhancing query efficiency. Without these indexes, MongoDB would have to sift through every document in a collection for query results. An available index can drastically reduce the number of documents MongoDB examines.
Benefits of using indexes
The benefits of indexes include the following:
- Performance boost: Indexes significantly speed up data retrieval operations, reducing the need to scan every document in a collection.
- Reduced load: By accelerating search queries, indexes decrease the system's workload, leading to better resource utilization.
- Sort efficiency: Indexes support efficient sorting operations, allowing results to be ordered without extra computational effort.
- Support for complex queries: Advanced query operations, such as geospatial searches or text- based searches, are made possible and efficient through specialized indexes. ...
