Datasource tenant configuration

Since CDS 2.1, the customerdata service supports multi-tenant datasources. Enabling multi-tenancy means that calling the API will require sending an additional HTTP header (X-TENANT-ID) with the tenant name. In the configuration of the customerdata service can configure which tenants are allowed to access the API and for each allowed tenant configure a specific datasource.  When the customerdata service is not able to retrieve the tenant name or the given tenant name is not allowed to access a HTTP Status 400 (Bad request) is returned and the details are printed in the log. 

We only support multi-tenancy where each tenant uses the same database vendor. You are not able to mix, for example, an Oracle tenant with an Microsoft SQL Server tenant.

Event publisher tenant configuration

Since CDS 4.4 the customerdata service supports a multi-tenant event publisher. Enabling multi-tenancy means that properties for publishing aggregate event messages to a queue can be configured for each tenant. To enable the event publisher the entity-event-publisher-amqp profile should be active.
