Community FAQ

Questions by product

Amazon DocumentDB FAQ

Can I self-host Amazon DocumentDB or is it exclusively a managed service?

Amazon DocumentDB is exclusively a fully managed service provided by AWS and cannot be self-hosted. It abstracts away the underlying infrastructure management, so you do not have access to host or operate the database outside AWS's managed environment.

Community insight informed by Reddit discussions

Does Amazon DocumentDB support offline or local development environments?

Amazon DocumentDB does not support offline or local deployments since it is a cloud-native managed service. For local development, you will need to run a MongoDB instance or use MongoDB Atlas's local emulators, then migrate to DocumentDB for production workloads.

Community insight informed by Hacker News discussions

What are the data ownership and export options with Amazon DocumentDB?

Data stored in Amazon DocumentDB remains your property, but AWS manages the underlying storage. You can export data using standard MongoDB tools like mongodump and mongorestore, or export snapshots to S3 for backup and migration purposes. However, some advanced MongoDB features may not be fully supported during export/import.

Community insight informed by StackOverflow discussions

Are there any API limitations or MongoDB feature gaps in Amazon DocumentDB I should be aware of?

Amazon DocumentDB supports a subset of MongoDB APIs compatible with MongoDB 3.6 and 4.0, but it lacks support for features like multi-document ACID transactions, certain aggregation pipeline stages, and some index types. These limitations can impact applications relying on advanced MongoDB features.

Community insight informed by Forums discussions

What is the recommended migration path from self-managed MongoDB to Amazon DocumentDB?

AWS recommends using the native MongoDB tools such as mongodump/mongorestore or AWS Database Migration Service (DMS) to migrate data. Due to compatibility differences, you should validate your application's MongoDB feature usage and test thoroughly to address any incompatibilities before fully switching to DocumentDB.

MongoDB Atlas FAQ

How much control do I have over data residency and ownership when using MongoDB Atlas compared to self-hosting?

With MongoDB Atlas, your data is hosted on cloud providers chosen during cluster setup, and while you retain ownership of your data, the physical storage and management are handled by Atlas. Unlike self-hosting, you cannot directly control the underlying infrastructure or storage environment, but Atlas provides compliance certifications and encryption to protect data privacy and residency requirements.

Community insight informed by Reddit discussions

Is it possible to run MongoDB Atlas clusters offline or in an air-gapped environment?

No, MongoDB Atlas is a fully managed cloud service and requires internet connectivity to the cloud provider's infrastructure. It does not support offline or air-gapped deployments. For offline or on-premise use cases, you would need to deploy MongoDB manually or use MongoDB Enterprise on your own infrastructure.

Community insight informed by Hacker News discussions

What are the limitations of MongoDB Atlas APIs for automation and integration compared to self-hosted MongoDB?

MongoDB Atlas provides a comprehensive REST API for cluster management, monitoring, and automation, but it does not expose the full range of internal database operations available in self-hosted MongoDB. Some administrative tasks, such as direct file system access or custom plugin installation, are not possible. However, for most operational workflows, the Atlas API is sufficient and well-documented.

Community insight informed by StackOverflow discussions

What is the recommended process for migrating existing self-hosted MongoDB databases to MongoDB Atlas?

The recommended migration path involves using MongoDB's native tools such as mongodump/mongorestore or MongoDB Atlas Live Migration Service, which enables near-zero downtime migration from self-hosted MongoDB to Atlas clusters. It is important to validate compatibility of MongoDB versions and to test the migration in a staging environment before production cutover.

Community insight informed by Forums discussions

How does MongoDB Atlas handle scaling and maintenance without requiring manual intervention?

MongoDB Atlas automates scaling by allowing users to configure cluster tiers and auto-scaling policies that adjust resources based on workload. Maintenance tasks such as patching, backups, and replication management are handled transparently by Atlas, reducing operational overhead compared to self-hosted setups where these require manual execution.
