Abstract
A distributed database keeps an abstract syntax tree (AST) and an included user code from interacting with a query engine coordinator during the performance of query execution processes. The query engine coordinator is separated into a frontend and backend, where a compiler on the frontend generates an AST and serializes it to be sent to the backend. The backend is implemented in a security environment separate from the front end. The backend deserializes the AST, sanitizes it, and generates a query plan based on the sanitized AST.
