What mongo-java-driver is

A JVM driver offering both sync and async APIs for MongoDB operations, supporting connection pooling, transactions, and modern language features (Kotlin coroutines, Scala). Built on Java 17+ and follows semantic versioning with documented Alpha/Beta/Deprecated API lifecycle.

Quickstart

Get the mongo-java-driver source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/mongodb/mongo-java-driver.gitcd mongo-java-driver# follow the project's README for install & configuration

Best use cases

Microservices and API backends

Ideal for building REST/GraphQL APIs and microservices in Java, Kotlin, or Scala that require reliable, transactional MongoDB connectivity with connection pooling.

Enterprise JVM applications

Suitable for large-scale enterprise systems where MongoDB is the primary datastore and driver stability, documentation, and vendor support are critical.

Multi-language JVM polyglot teams

Best fit for teams using Kotlin coroutines or Scala alongside Java, as the driver provides idiomatic APIs for all three languages.

Implementation considerations

  • Minimum Java 17+ required; verify JVM version compatibility before deployment.
  • Alpha and Beta APIs are subject to breaking changes; avoid in production libraries or platform code; use only in application code with vendor support awareness.
  • Connection pooling and resource management are automatic but must be tuned for workload (connection limits, timeouts) via MongoClient constructor parameters.
  • Test suite requires mongod instance with enableTestCommands enabled; set up local MongoDB for integration testing in CI/CD pipelines.
  • Semantic versioning is followed; monitor release notes for deprecations and plan upgrades to stay current with security and stability fixes.

When to avoid it — and what to weigh

  • Non-JVM platforms required — This is Java/JVM-only; use MongoDB drivers for Node.js, Python, Go, or other runtimes if targeting non-JVM environments.
  • No MongoDB involvement acceptable — If organizational policy prohibits vendor-provided drivers or requires community-only dependencies, this official driver may not align with governance rules.
  • Experimental/Alpha APIs needed in production — APIs marked @Alpha lack compatibility guarantees and are unsuitable for production; only @Stable or released APIs should be used in production code.
  • Minimal overhead required — If extremely lightweight connection handling is required, evaluate alternatives; the official driver carries full feature support and some operational overhead.

License & commercial use

Apache License 2.0 (Apache-2.0) is a permissive, OSI-approved open-source license. It permits commercial use, modification, and redistribution with appropriate attribution and liability disclaimer.

Commercial use is permitted under Apache 2.0. No license fee is required. However, as this is an official MongoDB driver, review MongoDB's commercial support terms separately if production support or indemnification is needed. The license itself does not provide vendor support or indemnification; those are separate commercial offerings.

Security considerations

No specific security vulnerabilities or posture details provided in data. Official MongoDB security vulnerability reporting process documented; report via MongoDB's vulnerability disclosure guidelines. Recommend: verify SSL/TLS support for transport security, apply latest driver patches promptly, use strong authentication (SCRAM, LDAP, etc.) when connecting, and audit connection strings in code before deployment. Internal APIs (com.mongodb.internal.*) are private and subject to change.

Alternatives to consider

Spring Data MongoDB

Higher-level abstraction over the Java driver; use if ORM-like query DSL, Spring integration, or transaction management within Spring Boot is needed.

Quarkus MongoDB driver or Vert.x MongoDB client

Preferred for reactive, event-driven architectures or GraalVM native image targets; lower latency than traditional driver.

MongoDB driver for other languages (Node.js, Python, Go)

Select if targeting non-JVM platforms or polyglot teams where native language drivers provide better idioms.

mongo-java-driver FAQ

Is Alpha API safe for production?
No. APIs marked @Alpha are experimental, subject to breaking changes, and lack compatibility guarantees. Use only in non-production code or application logic under vendor support.
Can I use the driver without MongoDB locally for tests?
Not recommended for integration tests. The test suite requires mongod with enableTestCommands. Use testcontainers or Docker for CI/CD, or mock for unit tests.
What is the difference between mongodb-driver-sync and mongodb-driver-reactive?
Sync is blocking, thread-pool based; Reactive uses async/non-blocking with Project Reactor. Choose based on your concurrency model (traditional threads vs. async pipelines).
How do I report security issues?
Follow MongoDB's vulnerability reporting instructions at https://www.mongodb.com/docs/manual/tutorial/create-a-vulnerability-report/. Do not email developers directly.
