Abstract: A distributed database keeps user-defined functions separate from a query engine by using a frontend. The frontend allows a user-defined function to interact with a proxy application processing interface (API) that is based on an API of the query engine. The frontend sends serialized data to the query engine in order to interact with the API of the query engine. The user-defined function is executed in security environments separate from the frontend and the query engine.

Abstract: A distributed database identifies classifications of risk associated with stages of a query plan. The distributed database generates an execution plan in which incompatible risk classifications are assigned to separate stages of an execution plan that is derived from the query plan. The stages are assigned to computing nodes for execution based, at least in part, on the risk classifications. A result for the query is generated based on execution of the stages on the assigned computing nodes.
