This presentation will take a look at the performance changes in the development version of PostgreSQL. A selection of features, some proposed and some already committed, are evaluated using synthetic open source workloads. One of the workloads used is the former OSDL's Database Test 3 that consists of business oriented ad-hob queries with concurrent data modification.
Some of these proposed features include:
- New index type called Block Range Indexes (BRIN)
- Improvements to the buffer cache management
- Improvements to the data lock management
- Other internal data structure changes
