Work easily with any data type

Get complete control over your data with the MongoDB Query API. It’s designed to handle any data structure with ease, including key-value, graph, geospatial, time series, and objects. Optimized for embedded arrays and objects, these expressive querying capabilities unlock the flexibility of the document model.

Boost productivity with a single interface

Unlock the full potential of data operations. Perform key operations, including: Indexing, querying, and updating.— all through a single, powerful API. And modernize your applications by using transactional, search, and analytical queries, without the need to switch between interfaces or struggle with complex query syntax.

Feature overview
mdb_query

Expressive querying

Use a wide range of powerful operators, like $elemMatch and $geoWithin to query and update one or more documents based on a combination criteria, including within nested arrays and objects.

general_features_global_clusters

Diverse index types

Optimize your queries with many index types — no matter how deeply nested the fields.

general_features_data_analytics

Geospatial and graph data

Query geospatial data easily and use operators, like $graphLookup, to traverse connected datasets.

atlas_data_federation

Query across collections and databases

Use $lookup and $unionWith to join and blend multiple collections, or Atlas Data Federation to query across databases, for deep analysis and exploration.

mdb_aggregation_pipelines

Transform + analyze data in place

Use the aggregation pipeline to build complex transformations in an easy, modular fashion.

atlas_full_text_search

Full-text search built for the document model

Deploy advanced, full-text search — without the need to manage additional infrastructure.

mdb_change_streams

Change streams

Build real-time, event-driven apps that react to database changes by triggering server-side logic.

mdb_materialized_views

On-demand, incremental materialized views

Pre-compute and cache common queries, dynamically updating result sets as new data is processed.

Simplify working with data

Work with your data in an intuitive, familiar way. Deliver data-driven applications with minimal code run queries, build complex aggregation pipelines, and power applications. All with your preferred language.

Expressive querying made easy
Easily query on a range of data types including geospatial, graph, time series, as well as on nested arrays and objects. The JSON-like syntax allows for treating data as objects, while language drivers enable working in your preferred language. The Query API simplifies working with data in your application code.
Composable in-database transformations
Build modular, multi-stage aggregation pipelines to run powerful analytics on your data. Query across collections and databases, and transform your data to the exact schema you need. Surface key insights and inform the decision-making process.
Full-text search, time series, and more
Use a single interface for creating complex queries that power search workloads, time-series workloads, and/or event-driven apps. Save time on integrating multiple APIs or complex ETL.
