Community FAQ

Questions by product

AWS Aurora PostgreSQL FAQ

Can AWS Aurora PostgreSQL be self-hosted or is it fully managed only?

AWS Aurora PostgreSQL is a fully managed database service and cannot be self-hosted. It runs exclusively on AWS infrastructure, providing automated backups, patching, and scaling, but you do not have access to the underlying host OS or database engine binaries to self-manage.

Community insight informed by Reddit discussions

Does AWS Aurora PostgreSQL support offline or disconnected database operations?

No, AWS Aurora PostgreSQL requires continuous connectivity to the AWS cloud environment. It is not designed for offline or disconnected usage since it relies on AWS managed storage and networking layers for durability and replication.

Community insight informed by Hacker News discussions

Who owns the data stored in AWS Aurora PostgreSQL and how is data privacy handled?

Data stored in AWS Aurora PostgreSQL remains the property of the customer. AWS acts as the data processor under the shared responsibility model. Customers control access via IAM policies and encryption keys, and AWS provides compliance certifications to support regulated workloads.

Community insight informed by StackOverflow discussions

Are there any API limitations or restrictions when using Aurora PostgreSQL compared to standard PostgreSQL?

Aurora PostgreSQL is highly compatible with standard PostgreSQL APIs and drivers, but some extensions or features that require superuser privileges may not be supported due to the managed environment. Additionally, certain replication and backup APIs are specific to Aurora's architecture.

Community insight informed by Forums discussions

What are the recommended migration or export paths from on-prem PostgreSQL to AWS Aurora PostgreSQL?

Common migration paths include using AWS Database Migration Service (DMS) for live replication with minimal downtime, pg_dump/pg_restore for offline migration, or logical replication slots. Aurora also supports importing snapshots from standard PostgreSQL backups with some manual adjustments.

Supabase FAQ

How complex is it to self-host Supabase for production use?

Self-hosting Supabase involves deploying multiple components including Postgres, the realtime server, auth services, storage, and edge functions. While the core is open-source, production hardening requires configuring backups, scaling, and security measures manually. The official Supabase GitHub repo provides docker-compose setups, but operational overhead is significant compared to managed hosting. Expect to invest in monitoring and maintenance infrastructure.

Community insight informed by Reddit discussions

Does Supabase support offline functionality or local-first data sync?

Supabase does not natively support offline-first or local data sync out of the box. Its realtime features rely on active WebSocket connections to sync data changes. For offline scenarios, developers need to implement client-side caching and conflict resolution manually or integrate with third-party libraries. This makes offline-first app development more complex compared to platforms designed specifically for local sync.

Community insight informed by Hacker News discussions

Who owns the data when using Supabase hosted services? Is there vendor lock-in?

Data stored in Supabase's hosted services remains fully owned by the user, as it is stored in PostgreSQL databases you control. Supabase is open-source, and you can export your data at any time. However, using hosted services means trusting Supabase infrastructure until you migrate or self-host. To avoid vendor lock-in, you can self-host or export your database and storage assets regularly.

Community insight informed by StackOverflow discussions

What are the API limitations when using Supabase's realtime and edge functions?

Supabase realtime APIs support subscriptions to Postgres changes but have limitations on complex query types and large-scale fanouts. Edge functions run in a serverless environment with execution time and resource constraints, which may not suit heavy compute tasks. Additionally, some advanced Postgres features or extensions might not be fully supported in realtime streams or edge functions.

Community insight informed by Forums discussions

How easy is it to migrate existing Postgres databases to Supabase?

Migrating an existing Postgres database to Supabase is straightforward since Supabase uses standard Postgres under the hood. You can dump your current database schema and data and restore it into Supabase. However, you may need to adapt authentication and storage integrations to Supabase's APIs. Also, Supabase-specific features like realtime or edge functions require additional setup post-migration.
