AI-powered tuning tools for Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL databases: PI Reporter

In this post, we explore an artificial intelligence and machine learning (AI/ML)-powered database monitoring tool for PostgreSQL, using a self-managed or managed database service such as Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL.

Migrate Oracle reference partitioned tables to Amazon RDS or Aurora PostgreSQL with AWS DMS

Database migrations from Oracle to PostgreSQL are becoming increasingly common as organizations seek to optimize database costs while leveraging the benefits of open-source database solutions. However, these migrations present specific challenges, particularly when dealing with an Oracle-specific feature such as reference partitioning, which doesn’t have a direct equivalent in PostgreSQL. In this post, we show you how to migrate Oracle reference-partitioned tables to Amazon RDS for PostgreSQL or Amazon Aurora PostgreSQL-Compatible Edition using AWS DMS.

Optimize and troubleshoot database performance in Amazon Aurora PostgreSQL by analyzing execution plans using CloudWatch Database Insights

In this post, we demonstrate how you can use Amazon CloudWatch Database Insights to analyze your SQL execution plan to troubleshoot and optimize your SQL query performance in an Aurora PostgreSQL cluster.

Monitoring multithreaded replication in Amazon RDS for MySQL, Amazon RDS for MariaDB, and Aurora MySQL

In this post, we discuss methods to effectively monitor parallel replication performance and tune its related parameters for Amazon Aurora MySQL and Amazon Relational Database Service for MySQL and MariaDB.

Overview and best practices of multithreaded replication in Amazon RDS for MySQL, Amazon RDS for MariaDB, and Amazon Aurora MySQL

In this first post, we dive into the world of MySQL replication, with a special focus on parallel replication techniques. We start with a quick overview of how MySQL replication works, then explore the intricacies of multithreaded replication. We discuss key configuration options and best practices for optimization.

Amazon Aurora MySQL zero-ETL integration with Amazon SageMaker Lakehouse

In this post, we explore how zero-ETL integration works, the key benefits it delivers for data-driven teams, and how it aligns with the broader zero-ETL strategy in AWS services. You’ll learn how this integration can enhance your data workflows, whether you’re building predictive models, entering interactive SQL queries, or visualizing business trends. By eliminating traditional extract, transform, and load (ETL) processes, this solution enables real-time intelligence securely and at scale to help you make faster, data-driven decisions.

Advanced observability and troubleshooting with Amazon RDS event monitoring pipelines

AWS provides a wide range of monitoring solutions for your Amazon RDS and Amazon Aurora instances, such as Amazon CloudWatch, Amazon CloudWatch Database Insights, and AWS CloudTrail. Amazon RDS event monitoring pipelines make troubleshooting operational events like reboots, errors, and failovers more efficient. In this post, we present a solution to get a head start on troubleshooting by sending an email after a reboot or failover with the last 10 minutes of important CloudWatch metrics, top queries, and related API calls performed on the instance.

Identifying and resolving performance issues caused by TOAST OID contention in Amazon Aurora PostgreSQL Compatible Edition and Amazon RDS for PostgreSQL

In this post, we explore the challenges of OID exhaustion in PostgreSQL, focusing on its impact on TOAST tables and how it leads to performance issues. We will cover how to identify the problem by reviewing wait events, session activity, and table usage. Additionally, we discuss practical solutions, from cleaning up data to more advanced strategies such as partitioning.

Long-term storage and analysis of Amazon RDS events with Amazon S3 and Amazon Athena

In this post, we show you how to implement an automated solution for archiving Amazon RDS events to Amazon Simple Storage Service (Amazon S3). We also discuss how to analyze the events with Amazon Athena which helps enable proactive database management, helps maintain security and compliance, and provides valuable insights for capacity planning and troubleshooting.
