title: Setting a Coordinator Configuration Parameter 
---

To set a coordinator configuration parameter, set it at the Greenplum Database coordinator instance. If it is also a *session* parameter, you can set the parameter for a particular database, role or session. If a parameter is set at multiple levels, the most granular level takes precedence. For example, session overrides role, role overrides database, and database overrides system.
