Achieve up to 1.7 times higher write throughput and 1.38 times better price performance with Amazon Aurora PostgreSQL on AWS Graviton4-based R8g instances

Upgrading to Graviton4-based R8g instances with Aurora PostgreSQL-Compatible 17.4 in an Aurora I/O-Optimized cluster configuration results in significant performance improvements. The new instances provide up to 1.7 times higher write throughput, 1.38 times better price-performance, and reduce commit latency by up to 46% on r8g.16xlarge instances and 38% on r8g.2xlarge instances compared to Graviton2-based R6g instances. The Amazon Aurora PostgreSQL-Compatible Edition now supports AWS Graviton4-based R8g instances and PostgreSQL 17.4, which introduces performance enhancements for I/O-Optimized configurations, optimizing write operations and batch processing. R8g instances offer up to 192 vCPUs and 1.5 TB of memory, supporting larger configurations and providing up to 50 Gbps of network bandwidth. PostgreSQL 17 includes vacuum improvements, eliminates the need to drop logical replication slots during upgrades, and expands SQL/JSON standards. Aurora PostgreSQL-Compatible separates compute from storage, enabling independent scaling and maintaining six-way replication for durability, while processing changes as log records to reduce I/O operations. Performance benchmarks using HammerDB show improvements in throughput and commit latency across various workloads. For small workloads on 2xlarge instance size, throughput increased by 50.25% and commit latency improved by 33.87%. For medium workloads on 16xlarge instance size, throughput increased by 30% and commit latency improved by 17.44%. The most significant performance benefits arise from combining hardware upgrades from Graviton2 to Graviton4 with database engine upgrades from PostgreSQL 15.10 to 17.4. For small workloads, throughput increased by 70% and commit latency improved by 38.71%. For medium workloads, throughput increased by 70% and commit latency improved by 46.67%. Cost efficiency is also enhanced, with a 38% improvement in price performance and a 61.26% improvement in price-performance ratio when comparing Graviton2 and Graviton4 instances. Reserved Instances for Graviton4-based R8g instances offer additional cost-optimization opportunities.

Running I/O intensive workloads on PostgreSQL with Amazon EBS io2 Block Express

Databases are essential for organizations, and their performance is critical to user experience and operational efficiency. AWS introduced Amazon Elastic Block Store (Amazon EBS) io2 Block Express in December 2020 to address performance issues related to storage latency during database operations. This solution enhances storage management for high-performance database servers, supporting up to 256,000 IOPS and 4,000 MiB/s throughput per volume, with a maximum volume size of 64 TiB and sub-millisecond disk I/O latency. A performance comparison was conducted between PostgreSQL databases on Amazon EBS gp3 and io2 Block Express, utilizing the HammerDB benchmarking tool. The analysis involved four tests: OLTP Load test, OLTP Stress test, OLAP Load test, and OLAP Stress test, using r5b.24xlarge EC2 instances. Results indicated that io2 Block Express outperformed gp3 by 2.08 times in transactions per minute (TPM) and provided significantly lower latency for both OLTP and OLAP workloads. Key differences between gp3 and io2 Block Express include durability, with io2 offering 99.999% durability compared to gp3's 99.8% – 99.9%. The maximum IOPS for gp3 is 16,000, while io2 supports up to 64,000 IOPS. Pricing for gp3 is approximately ,375.36/month, while io2 Block Express costs around ,408/month, reflecting its premium performance capabilities. In benchmarking tests, io2 Block Express demonstrated superior performance, achieving 3.95 times faster average performance than gp3 across all scenarios. It is particularly suitable for mission-critical applications requiring consistent sub-millisecond latency and high durability.
