URL: https://github.com/apache/asterixdb/pull/51
Adds a builtin datasource function that exposes the runtime function
registry as queryable rows: { name, arity, category, private }. Category is
derived from existing engine predicates (window, aggregate, aggregate-scalar,
unnest, datasource, scalar), letting clients filter instead of hardcoding
function lists.
- BuiltinFunctions.getBuiltinFunctionIdentifiers(): read-only registry
accessor
- FunctionMetadata{Rewriter,Datasource,Function,Reader}: modeled on
jobs()/active_requests()
- registered (public) in MetadataBuiltinFunctions
- runtime test under misc/function_metadata
