Project Introduction

Summary

This project, 'pgactive', offers an open-source solution and best practices for implementing an Active-Active PostgreSQL setup on AWS. It leverages advanced replication techniques to enable multiple writable database instances, enhancing application resilience and performance.

Problem Solved

Traditional PostgreSQL replication models (like primary/standby) only allow writes to a single primary, limiting scalability for write-heavy workloads and requiring failover time. This project addresses the need for true multi-primary write capability and continuous availability in a cloud environment.

Core Features

AWS-Specific Deployment

Automated setup scripts and configuration examples tailored for the AWS environment, simplifying deployment.

Active-Active Replication

Provides a mechanism for synchronous or asynchronous multi-primary replication, allowing writes to multiple nodes.

Failover & Consistency Management

Includes tools and strategies for handling node failures and maintaining data consistency across active primaries.

Tech Stack

PostgreSQL
AWS EC2
AWS VPC
Replication Mechanisms (e.g., BDR, pglogical/pgcat - *example, actual tech may vary*)
Linux (e.g., Ubuntu, Amazon Linux)
Shell Scripting/Infrastructure as Code (e.g., CloudFormation, Terraform - *example*)

Use Cases

An active-active PostgreSQL setup is beneficial for applications requiring continuous write availability and improved read/write performance across multiple locations or for disaster recovery.

Multi-Region Application Deployment

Details

Deploy an active-active cluster across multiple AWS regions to provide low-latency access for users globally and ensure business continuity in case of a regional outage.

User Value

Achieve regional fault tolerance and distribute read/write load geographically.

High-Traffic Web Applications

Details

Utilize multiple writable instances within a single AWS region across different Availability Zones to handle high volumes of concurrent writes and provide AZ-level high availability.

User Value

Improve write throughput and eliminate single points of failure within a region.
