Tuning PostgreSQL for High Write Workloads
In this session we will cover a number of the ways that you can tune PostgreSQL to better handle high write workloads. This will cover both application and database tuning methods as each type can have substantial benefits but can also interact in unexpected ways when you are operating at scale. On the application side we will look at write batching, use of GUID's, general index structure, the cost of additional indexes and impact of working set size. For the database we will see how wal compression, auto vacuum and checkpoint settings as well as a number of other configuration parameters can greatly affect the write performance of your database and application.
