What type of enhancement is this?

Configuration

What does the enhancement do?

User may send a large batch of PRW data while some of the entries has to be stored in particular namespace (database).

In PromQL query, we have __database__ meta label to route to certain namespace. On the ingestion side, we need similar mechanism too.
