PostgreSQL database servers have a common set of problems they encounter as their usage gets heavier and requirements more demanding. You could spend years discovering solutions to them all, step by step as you encounter them.
Or you can just look in here.All successful database applications are destined to eventually run into issues scaling up their performance. Know the warning signs to look for, and how to avoid the most common issues before they even happen.Surprisingly, most PostgreSQL database applications evolve in the same way: Choose the right hardware.
Monitor every layer, from hardware to queries, using some tools that are inside PostgreSQL and others that are external.Using monitoring insight, continuously rework the design and configuration. On reaching the limits of a single server, break things up; connection pooling, caching, partitioning, and replication can all help handle increasing database workloads.The path to a high performance database system isn't always easy.
