9 Step Performance Tuning AWS RDS PostgreSQL
As a 29-year veteran of MS SQL Server, I need to review and learn how do things in the Cloud world. So, I make notes as I learn. I hope that you enjoy.
9 Steps in Performance Tuning AWS RDS PostgreSQL Database
Here are some steps you can take to performance tune your AWS RDS PostgreSQL database:
1.??????Identify the slow PostgreSQL queries: Use the PostgreSQL logs to identify queries that are taking a long time to execute.
2.??????Optimize queries: Once you have identified slow queries, optimize them by rewriting them or by adding appropriate indexes.
3.??????Optimize database parameters: Adjust the PostgreSQL configuration parameters to optimize the database performance. This includes parameters such as the shared_buffers, work_mem, and maintenance_work_mem.
4.??????Monitor database performance: Use CloudWatch metrics to monitor the database performance. Monitor key metrics such as CPU utilization, disk I/O, and network traffic.

5.??????Scale up or out: If your database workload is growing, you may need to scale up or out your database instance. This can be done by upgrading your instance type or by adding read replicas.
6.??????Use caching: Consider using a caching layer such as Amazon ElastiCache to improve database performance. The other option is using a Hazelcast IMDG but I will look at that in a later post.
7.??????Use Amazon RDS Performance Insights: Use Amazon RDS Performance Insights to monitor database performance and identify performance issues.
8.??????Implement database sharding: If your database is very large and cannot be scaled up or out, consider implementing database sharding. This involves splitting the database into smaller pieces that can be managed separately.
9.??????Regularly maintain the database: Regularly perform database maintenance tasks such as vacuuming, analyzing, and reindexing to optimize performance.
Overall, performance tuning is an ongoing process and requires constant monitoring and optimization.
I will add a post explaining how to set up Logging and then how to use the results. I realized that I mentioned Logging without explaining how to do it.
