Databroker Storage Settings
The databroker service manages all persistent state within Pomerium. These settings control how the databroker service will store this state.
For more information on the databroker service see Persistence & Data storage.
Databroker Storage Type
Databroker Storage Type sets the backend storage type:
memory— data is stored in main memoryfile— data is stored in a local directorypostgres— data is stored in an external PostgreSQL database
The in-memory option is sufficient for single-replica Pomerium deployments. A PostgreSQL database is required when running multiple replicas of Pomerium, in order to ensure that all replicas share a consistent view of the application state.
