Automate Oracle PL/SQL to PostgreSQL migration with Amazon Bedrock and Strands Agents

In this post, you learn how to build a generative AI–powered migration assistant that helps automate portions of the last mile of code conversion. Using Anthropic’s Claude Sonnet 4.6 on Amazon Bedrock, the Strands Agents framework, and the AWS Knowledge MCP Server, you can automate the conversion and validation of PL/SQL objects against Amazon Aurora PostgreSQL-Compatible Edition. The assistant reads the AWS DMS SC assessment CSV, fetches live PL/SQL source from Oracle, converts each object, deploys the result to Aurora PostgreSQL through AWS Lambda, and runs automated tests, in a single pipeline.

Building Python applications with SQLAlchemy and Aurora DSQL

In this post, you’ll build a working veterinary clinic command line interface (CLI) application that demonstrates production-ready patterns for connecting SQLAlchemy to Aurora DSQL. The patterns you implement (UUID primary keys, application-level relationships, and AUTOCOMMIT engine configuration) apply to other Python ORMs on Aurora DSQL.

Oracle Database@AWS decoded: Determining the right fit for your Oracle workloads

In this post, we explore the key reasons why Oracle Database@AWS is a strong fit for organizations running Oracle workloads on AWS. We cover the business, technical, and licensing advantages it brings, and how it complements the existing AWS options you already know, such as Amazon RDS for Oracle and Amazon EC2.

Understanding how backups work in Amazon Aurora

In this post, we dive deep into the Aurora backup architecture, how it differs from Amazon RDS backups, and the Amazon CloudWatch metrics available to monitor your backup storage usage. Through detailed scenarios and visualizations, we demonstrate how workload patterns and retention periods impact backup costs. We also explore cross-Region backup options and share recommended practices to optimize your backup storage consumption.

Index types supported in Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL using extensions (Bloom, pg_trgm, and pg_bigm)

In Part 1, Part 2, and Part 3 of this series, we explored PostgreSQL’s native indexes (B-tree, GIN, GiST, HASH, BRIN) and specialized extension-based index types (SP-GiST, btree_gin, btree_gist). In this post, we dive into three additional extensions: Bloom (for space-efficient multi-column equality filtering), pg_trgm (for fuzzy text matching and similarity searches), and pg_bigm (for full-text search optimized for Asian languages)

Index types supported in Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL using extensions (SP-GiST, Btree_Gin and Btree_Gist)

In this post, the third in the series, we dive into three extension-based index types: SP-GiST, btree_gin, and btree_gist. These are available in Amazon Aurora PostgreSQL-Compatible Edition and Amazon Relational Database Service (Amazon RDS) for PostgreSQL. PostgreSQL’s index infrastructure is extensible. Operator classes define how indexes behave for specific data types and operations. The SP-GiST, btree_gin, and btree_gist extensions take advantage of this extensibility to give you additional indexing strategies beyond the native options. We walk through when to use each extension, the data types they support, and practical examples that demonstrate their performance benefits.

Implementing real-time change data capture with Debezium for Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL

In this post, we demonstrate how to implement a production-ready CDC solution by using Amazon Aurora for PostgreSQL, Debezium connectors, and Amazon Managed Streaming for Apache Kafka (Amazon MSK). This solution captures database changes in real time and streams them to Kafka topics so that downstream consumers can process the same data for different business purposes.
