In this post, we discuss configurations in AWS DMS endpoints and AWS DMS tasks to migrate spatial columns from Oracle to Aurora PostgreSQL-Compatible efficiently.

Vacasa is North America’s leading vacation rental management platform, revolutionizing the rental experience with advanced technology and expert teams. In the competitive short-term vacation property management industry, efficient systems are critical. To maintain its edge and continue providing top-notch service, Vacasa needed to modernize its primary transactional database to improve performance, provide high availability, and reduce costs. In this post, we share Vacasa’s journey from Amazon Relational Database Service (Amazon RDS) for MariaDB to Amazon RDS for MySQL, and finally to Amazon Aurora, highlighting the technical steps taken and the outcomes achieved.

In this post, we discuss integer sequence overflow, its causes, and—most importantly—how to efficiently set up alerts using Amazon SNS and use AWS Lambda to resolve such issues in Amazon Aurora PostgreSQL-Compatible Edition and Amazon RDS for PostgreSQL.

In this post, we focus on working with the features of mysql_fdw PostgreSQL extension on Amazon RDS for PostgreSQL to help manage a large set of data that on an external database scenarios. It enables you to interact with your MySQL database for importing individual/large/selectively number of objects at the schema level and simplifying how we get information about the MySQL/MariaDB schema, to make it easier to ultimately read/write data. We will also provide an introduction to understand query performance on foreign tables.

In this post, we provide details on two PostgreSQL plugins available for use by AWS DMS. We compare these plugin options and share test results to help database administrators understand the best practices and benefits of each plugin when working on migrations.

The zero-ETL integrations for Amazon Redshift are designed to automate data movement into Amazon Redshift, eliminating the need for traditional ETL pipelines. With zero-ETL integrations, you can reduce operational overhead, lower costs, and accelerate your data-driven initiatives. This enables organizations to focus more on deriving actionable insights and less on managing the complexities of data integration. In this post, we discuss the best practices for migrating your ETL pipeline from AWS DMS to zero-ETL integrations for Amazon Redshift.

FundApps, founded in 2010, is one of the pioneers in the Regulatory Technology (RegTech) space, which includes compliance monitoring and reporting. FundApps decided to rearchitect their environment and transform it to a cloud-based architecture on AWS to better support the growth of their business. For more information, see Faster, cheaper, greener: Pick three — FundApps modernization journey. In this post, we focus on the persistence layer of the FundApps regulatory data service. You learn how FundApps improved the service scalability, reduced cost, and streamlined operations by migrating from SQL Server database to a cloud-centered solution combining Amazon Aurora Serverless v2 with Babelfish for Aurora PostgreSQL and Amazon Simple Storage Service (Amazon S3).

In How the Amazon Timehub team built a data replication framework using AWS DMS: Part 1, we covered how we built a low-latency replication solution to replicate data from an Oracle database using AWS DMS to Amazon Aurora PostgreSQL-Compatible Edition. In this post, we elaborate on our approach to address resilience of the ongoing replication between source and target databases.

In this post, we look at two capabilities in Amazon Bedrock Knowledge Bases that make it easier to build RAG workflows with Amazon Aurora Serverless v2 as the vector store. The first capability helps you easily create an Aurora Serverless v2 knowledge base to use with Amazon Bedrock and the second capability enables you to automate deploying your RAG workflow across environments.

In this post, we dive deep into concurrency control, providing valuable insights into crafting efficient transaction patterns and presenting examples that demonstrate effective solutions to common concurrency challenges. We also include a sample code that illustrates how to implement retry patterns for seamlessly managing concurrency control exceptions in Amazon Aurora DSQL (DSQL).
