In this series of posts, we discuss index types supported in Amazon Aurora PostgreSQL-Compatible edition and Amazon Relational Database Service (Amazon RDS) for PostgreSQL and their use cases. In this post, we discuss the native B-tree index and its variations.

Key considerations when choosing a database for your generative AI applications

In this post, we explore the key factors to consider when selecting a database for your generative AI applications. We focus on high-level considerations and service characteristics that are relevant to fully managed databases with vector search capabilities currently available on AWS. We examine how these databases differ in terms of their behavior and performance, and provide guidance on how to make an informed decision based on your specific requirements.

Synopsis of several compelling features in PostgreSQL 16

In this post, we explore the new features in PostgreSQL 16 and discuss how they improve performance and query speed.

How to clone master user permissions in Amazon RDS for SQL Server

When you create a new Amazon Relational Database Service (Amazon RDS) for SQL Server instance, the master user is granted certain privileges for that database instance. We strongly recommend that you do not use the master user directly in your applications. Instead, adhere to the principles of least privilege and best practices by using a database user created with the minimal permissions required for your application. In this post, we discuss how to clone the master user to a new login and review it for the minimal permissions required.

AWS DMS homogenous migration from PostgreSQL to Amazon Aurora PostgreSQL

With AWS DMS homogenous migration, you can migrate data from your source database to an equivalent engine on AWS using native database tools. In this post, we show you an example of a complete homogeneous migration process and provide troubleshooting steps for migrating from PostgreSQL to Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL.

Configure SSL encryption on an SAP ASE source endpoint in AWS DMS

In this post, we walk you through how to configure Secure Sockets Layer (SSL) encryption between the source endpoints in AWS DMS and an on-premises SAP ASE source for secure data transfer. We also show you the steps for enabling SSL on an on-premises SAP ASE database. Configuring SSL encryption on source endpoints enables encrypting data in transit during the database migration process for enhanced security.

Automate cross-account backup of Amazon RDS for Oracle including database parameter groups, option groups and security groups

In this post, we showcase AWS Backup and CloudFormation support feature of AWS Backup to automate the backup of Amazon RDS for Oracle, including customized database resources such as database parameter group, option group, and security group across AWS accounts.

Perform a two-step database migration from an on-premises Oracle database to Amazon RDS for Oracle using RMAN

In this post, we discuss how to perform a homogeneous migration from an on-premises Oracle database to Amazon Relational Database Service (Amazon RDS) for Oracle. For our solution, we use a two-step approach to migrate the source database to Amazon RDS for Oracle. First, we use RMAN to restore the RMAN backup on an EC2 instance, then we use Data Pump to export data to Amazon S3 and restore that in the RDS for Oracle database.
