Configure Amazon Aurora PostgreSQL database activity streams for monitoring in IBM Guardium

In this post, we guide you through the steps to setting up Amazon Aurora PostgreSQL-Compatible Edition database activity streams (DAS) for monitoring in IBM Guardium. Here, we are using IBM Guardium version 11.5. Aurora PostgreSQL-Compatible is a fully managed, PostgreSQL-compatible, ACID-compliant relational database engine that combines the speed, reliability, and manageability of Amazon Aurora with […]

Introducing the Advanced JDBC Wrapper Driver for Amazon Aurora

Today’s modern applications are expected to be scalable and resilient. The top of this list is scalability, which depending on the size of the application workload could mean the ability to handle millions of users on demand. With stateful applications such as eCommerce, Financial Services and Games, this means having highly available databases. With the release of Amazon Aurora in 2015, customers could run relational databases in an Aurora cluster comprising of one writer and up to 15 low-latency reader nodes. This enables applications to scale reads significantly. However, as with any database supporting multiple instances, developers have built complex application logic to deal with special events such as switchover or failover.

Create custom PostgreSQL data types using Trusted Language Extensions

In this post, we demonstrate how to create custom PostgreSQL data types using TLE. PostgreSQL ships with many robust data types that accommodate most customer workloads in a performant manner. Although PostgreSQL has the capabilities to deploy custom data types natively, introducing new data types at scale in architectures spanning multiple AWS accounts and Regions poses a unique challenge for builders. With Trusted Language Extensions (TLE), you can create and manage your custom data types, allowing the quick and easy deployment of PostgreSQL data types across your infrastructures in a secure and efficient manner.

Introducing Amazon RDS Extended Support for Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL 11

Amazon Aurora PostgreSQL-Compatible Edition and Amazon Relational Database Service (Amazon RDS) for PostgreSQL major versions are supported at least until the community end-of-life for the corresponding community versions. When the community PostgreSQL major version reaches its end of life, no further updates, security patches, or bug fixes are released by the community. Aurora PostgreSQL 11 clusters […]

Manage case-insensitive data in PostgreSQL

It’s important to be aware of the case sensitivity of text data in PostgreSQL when performing queries or comparisons to ensure that the results match your intended expectations. Case also affects how the database performs sorting operations. By default, PostgreSQL is case sensitive when sorting or comparing string values. For example, PostgreSQL considers “amazon” and […]

Amazon Aurora PostgreSQL: cross-account synchronization using logical replication

In this post, we show you how to set up cross-account logical replication using Amazon Aurora PostgreSQL-Compatible Edition. By leveraging Aurora’s cross-account clone and PostgreSQL logical replication, you can achieve near real-time synchronization between a source and a target database in different AWS accounts. You can customize the solution to meet specific requirements, including selective […]

The role of vector datastores in generative AI applications

Generative AI has captured our imagination and is transforming industries with its ability to answer questions, write stories, create art, and even generate code. AWS customers are increasingly asking us how they can best take advantage of generative AI in their own businesses. Most have accumulated a wealth of domain-specific data (financial records, health records, […]

Migrate data from Amazon Aurora PostgreSQL to Amazon MemoryDB for Redis using AWS DMS

A common challenge customers face as their business grows is providing the same level of service to their end-users. Most often, databases become bottlenecks as usage outgrows capacity. Caching strategies may help improve performance by offloading frequently used data to a cache like Redis. This requires additional overhead in keeping your cache up to date. […]

PostgreSQL architecture considerations for application developers: Part 1

Although the application layer is the portion the world accesses for many cloud architectures, it seems that we rarely consider how we can optimize our application for the database we’re using. When using any relational database engine, it’s important to consider not just schema design, but understanding how databases read and write data to their […]

Leverage pgvector and Amazon Aurora PostgreSQL for Natural Language Processing, Chatbots and Sentiment Analysis

March 2024: This post was reviewed and updated to include Amazon Bedrock models (Titan and Anthropic Claude). Generative AI – a category of artificial intelligence algorithms that can generate new content based on existing data — has been hailed as the next frontier for various industries, from tech to financial services, e-commerce and healthcare. And […]
