Optimize your self-managed PostgreSQL data warehouse with Amazon FSx for OpenZFS

This article demonstrates how to optimize self-managed PostgreSQL data warehouses on AWS using Amazon FSx for OpenZFS to achieve significant storage compression, faster data reloads, and cost savings.

• Deploy primary PostgreSQL database on EC2 in one Availability Zone with read replica in another for resilience and cost optimization
• Use FSx for OpenZFS Single-AZ (HA) deployment with NFS protocol for shared storage access across EC2 instances
• Configure ZSTD compression at storage layer to reduce storage footprint by up to 74% while freeing host CPU resources
• Optimize NFS mount parameters (nconnect=16, rsize/wsize=1048576, sync, hard) for high performance and durability
• Implement PostgreSQL asynchronous replication between primary and replica for near real-time data copying with RPO under 1 minute
• Use AWS DMS for data synchronization from production OLTP databases to the data warehouse
• Enable daily automated FSx snapshots with 30-day retention and AWS Backup for comprehensive data protection
• Customer achieved 86% improvement in full data reload time (36 hours to 5 hours) and $60,000 annual storage cost savings

FSx for OpenZFS provides a scalable, resilient, and cost-effective storage foundation for self-managed PostgreSQL data warehouses aligned with AWS Well-Architected Framework principles.
