Aurora DSQL: Create a Serverless Cluster and Connect with PostgreSQL Client
- Aurora DSQL is a distributed SQL database service available in a free preview, replacing Amazon RDS Aurora. It uses PostgreSQL code for SQL processing over a distributed transaction and storage engine, unlike any other databases available under the Amazon Aurora umbrella.
- This service has a different runtime behavior, necessitating adjustments to align with its runtime behavior. It is compatible with the PostgreSQL wire protocol and dialect, requiring AWS Identity and Access Management (IAM) for authentication.
- The article provides a visual tutorial on how to connect to the Aurora DSQL serverless cluster using a PostgreSQL client, which requires generating a short-lived token for admin authentication.
- The article also highlights the notable database features, including IAM mapping, admin role creation, and short-lived generated password format, providing advantages in matters of security and authentication.
- The only allowed SSL mode on Aurora DSQL is 'require.' The article details how to create environment variables for the connection with the help of the AWS CLI.
- This article provides a comprehensive guide to connecting to Aurora DSQL databases using a PostgreSQL client while also summarizing the main sources of confusion that can be encountered on the way.
- This article serves as the first in a series of articles that will test and provide insights into Aurora DSQL's architecture and trade-offs in reproducible tests on the preview, available documentation, and publicly announced roadmap details.
- The upcoming series will also explore the many features and details of Aurora DSQL and highlight how it differs from YugabyteDB, the other distributed SQL database using PostgreSQL code.
