The Guide talks about Teradata REST Services as a "container", and REST API for Teradata Database as the first service deployed in this container. So how does one go about creating their own REST API ? The Guide doesn't mention the creation of new services. So I'm wondering if this is a mechanism for Teradata to deploy additional Teradata supplied APIs, or is the intention for customers to add their own to the "container" ? If the latter is true, are there any guidelines ?
