What Is Database Branching?
Database branching is a workflow where teams create isolated database branches from a common baseline to test schema and data changes without impacting shared environments.
Why It Matters for PostgreSQL Performance
In PostgreSQL performance work, branching helps teams test tuning and migration changes in parallel while reducing production blast radius.
Practical Benchmarking Context
When benchmarking with pgbench, compare baseline and branch runs using identical scale, concurrency, and load-generator location.
Use this term together with workload shape, concurrency level, and scale factor when interpreting pgbench outputs. Isolated values can be misleading without full run context.
Example
Example: Spin up one branch for migration testing and another for benchmark verification before merging to production.
