Can you say a couple of words about performance of the api and when it is advised to use scheduled requests rather than at hoc requests?

Christiaan Meihsl

Choosing between scheduled requests and ad hoc requests is often more a question of workflow than performance:

• Ad hoc requests are run on the fly, nothing is saved on the DSS server.
• Scheduled requests are usually recurring requests. They use a predefined instrument list and report template, that must be defined and saved on the DSS server prior to defining the schedule. For many of our customers, in time the report template will remain the same, whereas the instrument might vary slightly to include new instruments (and discard expired one).

For considerations on performance, see the tuning document in the Development section of the DSS REST documents.
