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.

CockroachDB FAQ

How complex is it to self-host CockroachDB in a multi-region setup compared to managed services?

Self-hosting CockroachDB in a multi-region configuration requires careful orchestration of nodes across different geographic locations, network latency considerations, and consistent cluster configuration. Unlike managed services, you must handle node provisioning, TLS certificates, backups, and failure recovery manually. The operational overhead is significant, especially ensuring reliable inter-region communication and maintaining consensus. However, CockroachDB provides detailed documentation and tooling to assist with these tasks.

Community insight informed by Reddit discussions

Does CockroachDB support offline functionality or local caching for edge use cases?

CockroachDB does not natively support offline mode or local caching on client devices. Its architecture relies on a distributed consensus protocol requiring nodes to be online and connected to maintain strong consistency. For edge scenarios, you would need to implement an external caching layer or sync mechanism, as CockroachDB itself expects all nodes to participate in the cluster quorum to serve consistent reads and writes.

Community insight informed by Hacker News discussions

How does CockroachDB handle data ownership and compliance when deployed across multiple regions?

CockroachDB allows you to configure data locality zones and constraints to ensure data resides in specific geographic regions, which helps meet data sovereignty and compliance requirements. You retain full ownership of your data when self-hosting, and the database does not perform any external data processing outside your control. Managed cloud offerings also provide region-specific deployment options to comply with local regulations.

Community insight informed by StackOverflow discussions

Are there any limitations or differences in CockroachDB's SQL API compared to standard PostgreSQL?

While CockroachDB offers PostgreSQL-compatible SQL, it does not support all PostgreSQL extensions, procedural languages, or some advanced features like certain window functions and full-text search capabilities. Its SQL dialect is evolving but may require query adjustments or workarounds for complex PostgreSQL-specific features. Additionally, performance tuning and indexing strategies differ due to its distributed architecture.

Community insight informed by Forums discussions

What are the recommended migration or export paths from PostgreSQL to CockroachDB?

The recommended migration path involves exporting PostgreSQL schema and data using tools like pg_dump (in plain SQL format) and then adapting the schema to CockroachDB's supported features. CockroachDB provides a migration guide that highlights incompatible data types and features. Data import can be done via SQL execution or bulk import tools like `cockroach sql` or `IMPORT`. Testing and iterative schema adjustments are crucial to ensure compatibility and performance.
