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.

Couchbase Capella FAQ

Is it possible to self-host Couchbase Capella or is it strictly a managed cloud service?

Couchbase Capella is offered exclusively as a managed cloud service and does not support self-hosting. For on-premises deployments, you would need to use Couchbase Server, which provides similar NoSQL capabilities but requires manual management and infrastructure setup.

Community insight informed by Reddit discussions

Does Couchbase Capella support offline or local-first data access for mobile or edge applications?

Couchbase Capella itself is a cloud-hosted managed service and does not provide offline or local-first capabilities directly. However, Couchbase offers Couchbase Lite, a mobile database that can sync with Capella via Sync Gateway, enabling offline data access and synchronization for edge or mobile apps.

Community insight informed by Hacker News discussions

What are the data ownership and export options available with Couchbase Capella?

Data stored in Couchbase Capella remains the customer's property, and the platform provides APIs and tools for data export, including backup and restore features. You can export data using N1QL queries or built-in backup utilities to JSON or CSV formats. However, migrating data out may require adapting to Capella's data model and query syntax.

Community insight informed by StackOverflow discussions

Are there any API or query limitations in Couchbase Capella compared to Couchbase Server?

Couchbase Capella supports the full N1QL query language and key-value operations similar to Couchbase Server. However, certain advanced administrative APIs and custom plugin capabilities available in Couchbase Server are restricted or managed by Capella's platform to ensure stability and security in the managed environment.

Community insight informed by Forums discussions

What should I consider when migrating from MongoDB to Couchbase Capella?

Migrating from MongoDB to Couchbase Capella requires careful planning because of differences in data models and query languages. You will need to transform MongoDB BSON documents to Couchbase JSON documents and rewrite queries from MongoDB's query language to N1QL. Additionally, application code changes are often necessary to accommodate differences in indexing and consistency models.
