This is the second post of a two-part series. In Part 1, we explored how you can use Automatic Data Optimization (ADO) and Oracle Information Lifecycle Management (ILM) policies for data compression. In this post, we demonstrate how to use Heat Map statistics to monitor data usage and integrate this information with hybrid partitioning and ILM data movement policies to move data to more cost-effective storage solutions.

In this two-part series, we demonstrate how to optimize storage for Oracle database workloads on AWS by using Oracle’s built-in features, such as Heat Map, Automatic Data Optimization (ADO), and hybrid partitioning. These features help classify data by its lifecycle stage and automate data management tasks to significantly reduce storage costs, while enhancing database performance, especially for growing datasets. In this post, we explore how to use ADO and Oracle ILM policies to automatically compress data based on usage patterns.

In this post, we guide you through the process of benchmarking the performance of Amazon RDS for PostgreSQL using the Dedicated Log Volume (DLV) feature. To do this, we use pgbench – a tool for running benchmark tests on PostgreSQL databases, pgbench repeatedly executes a defined sequence of SQL commands across multiple concurrent database sessions. Through our benchmarking, you’ll learn how to quantify the performance improvements delivered by DLV.

We’re introducing warm throughput, a new capability that provides insight into the throughput your DynamoDB tables and indexes can instantly support and allows you to pre-warm for optimized performance. In this post, we’ll introduce warm throughput, explain how it works, and explore the benefits it offers for handling high-traffic scenarios. We’ll also cover best practices and practical use cases to help you make the most of this feature for your DynamoDB tables and indexes.

Infrastructure as Code (IaC) is the practice of provisioning and managing your computing infrastructure using code, rather than manual processes and settings. Popular IaC tools, services, and platforms include Terraform, AWS CloudFormation, Ansible, and Pulumi, each offering unique features to automate and manage infrastructure across various cloud environments. In this post, we demonstrate how Terraform, one of our partner products, can be used to deploy and manage RDS for Db2 instance.

By combining DynamoDB streams with Lambda, you can build responsive, scalable, and cost-effective systems that automatically react to data changes in real time. In this post, we explore best practices for architecting event-driven systems using DynamoDB and Lambda. DynamoDB provides two options for capturing data changes (CDC): DynamoDB streams and Amazon Kinesis Data Streams (KDS). In this post, we focus exclusively on DynamoDB streams.

In this post, we show you how to use Amazon ElastiCache as a write-through cache for an application that uses an Amazon Keyspaces (for Apache Cassandra) table to store data about book awards. We use a Cassandra Python client driver to access Amazon Keyspaces programmatically and a Redis client to connect to the ElastiCache cluster.

In this post, AWS Service Sector Industry Solutions shares our journey in developing a feature that enables customers to efficiently locate and delete personal data upon request, helping them meet GDPR compliance requirements. The mission of the Service Sector Solutions Engineering Team is to accelerate AWS Cloud adoption across diverse industries, including Travel, Hospitality, Gaming, and Entertainment. We work with customers from Cruise Lines, Lodging, Alternative Accommodation, Travel Agencies, Airports, Airlines, Restaurants, Catering, Casinos, Lotteries, and more.

In certain customer scenarios, Amazon RDS for Oracle databases need to connect to external data sources, such as RDS for PostgreSQL. PostgreSQL can establish connections to Oracle databases using a foreign data wrapper (FDW). In this post, we walk you through setting up an EC2 instance as a database gateway server. You will install and configure Oracle Database Gateway for ODBC (DG4ODBC), ODBC drivers, a PostgreSQL client, and PostgreSQL libraries. With this setup, you can create database links on RDS for Oracle to connect to PostgreSQL through this gateway.

In our previous post, Capture and tune resource utilization metrics for Amazon RDS for SQL Server,’ we demonstrated how to use Amazon RDS Enhanced Monitoring and Amazon RDS Performance Insights to diagnose and debug CPU utilization bottlenecks for Amazon Relational Database Service (Amazon RDS) for SQL Server. Aside from CPU and memory, I/O performance is critical for overall database performance. It’s important to understand the I/O requirements of a SQL Server workload, which is dependent on various factors like query access patterns, database schema, and state of database maintenance. Understanding your workload’s, I/O patterns can guide you in selecting the optimal storage type for your RDS instance, balancing performance needs with cost-effectiveness. In this post, we demonstrate how you can use Amazon RDS monitoring tools along with SQL Server monitoring capabilities to capture, diagnose, and resolve I/O issues on an RDS for SQL Server instance.
