Migrating Amazon RDS for PostgreSQL to Amazon Aurora using seeded logical replication
In this post, we show you how to migrate from an Amazon RDS for PostgreSQL to Amazon Aurora PostgreSQL-Compatible Edition using seeded logical replication. For live migrations with minimal downtime, AWS provides several approaches, including Aurora read replicas, the snapshot/restore method combined with ongoing replication, and AWS DMS.
Amazon Aurora DSQL connections: Drivers, strings, and best practices
Connecting to Amazon Aurora DSQL requires a different approach than traditional PostgreSQL databases. Instead of long-lived passwords, you use short-lived IAM authentication tokens. Instead of static endpoints, you work with distributed cluster endpoints that route connections across Availability Zones. In this post, you learn how to configure connection strings, set up drivers in Python, Java, and Node.js, and implement best practices for authentication, connection pooling, and lifecycle management with Amazon Aurora DSQL.
Query billion-scale vectors with SQL: Integrating Amazon S3 Vectors and Aurora PostgreSQL
In this post, you’ll learn how to query Amazon S3 Vectors from Amazon Aurora PostgreSQL-Compatible Edition using standard SQL, and how to combine vector similarity results with relational filters in a single query, for example, finding the most semantically similar products and then filtering by price, stock status, or tenant in one SQL statement.
Migrating data from an Amazon Aurora snapshot into Amazon Aurora DSQL
In this post, we demonstrate how to use AWS Glue to migrate data from an Amazon Aurora database snapshot into an Aurora DSQL cluster.
Amazon Aurora DSQL for global-scale financial transactions
In this post, we first examine why traditional approaches to distributed consistency fall short for financial workloads. We then walk through how the Amazon Aurora DSQL architecture addresses these challenges, and apply it to three production use cases: core banking, global spend management, and digital currency infrastructure. We close with implementation considerations and how to get started with the Amazon Aurora DSQL Free Tier
DSQL SQL Dialect: How Amazon Aurora DSQL differs from single-instance PostgreSQL
This post is for database architects, developers, and DBAs who must evaluate Amazon Aurora DSQL or work with PostgreSQL workloads on a distributed database. Knowing exactly where Amazon Aurora DSQL aligns with standard PostgreSQL and where it diverges helps you to reduce risk and design schemas that perform well from day one. You might find that most existing PostgreSQL applications work with minimal changes.
How Kajabi optimized costs with Amazon Aurora upgrades
In this post, we show you how Kajabi navigated complex Aurora PostgreSQL database upgrades and achieved an 80.53% cost reduction through strategic planning and technical execution. You’ll discover their hybrid approach combining Amazon Aurora blue/green deployments with PostgreSQL native replication. You’ll also learn about their implementation of Aurora I/O-Optimized storage and the key lessons from their journey. Whether you’re managing large-scale databases or planning your own upgrade path, Kajabi’s experience offers valuable insights. You’ll see how to balance performance requirements with cost optimization while maintaining continuous availability.
Ring’s Billion-Scale Semantic Video Search with Amazon RDS for PostgreSQL and pgvector
In this post, we share Ring’s billion-scale semantic video search on Amazon RDS for PostgreSQL with pgvector architectural decisions vs alternatives, cost-performance-scale challenges, key lessons, and future directions. The Ring team designed for global scale their vector search architecture to support millions of customers with vector embeddings, the key technology for numerical representations of visual content generated by an AI model. By converting video frames into vectors-arrays of numbers that capture what’s happening (visual content) in each frame – Ring can store these representations in a database and search them using similarity search. When you type “package delivery,” the system converts that text into a vector and finds the video frames whose vectors are most similar-delivering relevant results in under 2 seconds.
Aurora serverless: Faster performance, enhanced scaling, and still scales down to zero
Amazon Aurora Serverless is an on-demand, auto scaling configuration for Aurora that scales up to support your most demanding workloads and down to zero when you don’t need it. The latest improvements deliver up to 30% better performance and enhanced scaling that understands your workload. These enhancements are available at no additional cost for a better price-performance ratio. In this post, we’ll share recent performance and scaling improvements with benchmark results, showing how Aurora Serverless can now scale up to 45.0% faster with a 32.9% faster workload completion time.
Build resilient Kerberos authentication for Aurora Global Database without joining Active Directory domain
In this post, we show you how to build a multi-Region Kerberos authentication system that matches your Aurora Global Database’s resilience using AWS Directory Service for Microsoft Active Directory (AWS Managed Microsoft AD) with multi-Region replication and a one-way forest trust to your on-premises Active Directory, so your Linux clients can authenticate without joining the AD domain.
