Class FHIRDbTenantDatasourceConnectionStrategy

java.lang.Object

com.ibm.fhir.persistence.jdbc.connection.FHIRDbConnectionStrategyBase

com.ibm.fhir.persistence.jdbc.connection.FHIRDbTenantDatasourceConnectionStrategy

All Implemented Interfaces:

FHIRDbConnectionStrategy, QueryHints

public class FHIRDbTenantDatasourceConnectionStrategy
extends FHIRDbConnectionStrategyBase

Hides the logic behind obtaining a JDBC Connection from the DAO code. Uses datasource and tenant ids configured in the fhir-server-config to map directly to a managed datasource. All managed datasources must be available when the server starts. This differs from the proxy datasource strategy FHIRDbPropsConnectionStrategy which supports dynamic (programmatic) definition of managed datasources.
