User-Defined Node
A User-Defined Node, or UDN, is any Node whose Node Type was customized or created outside the built-in defaults. UDNs include duplicated default types and entirely new types built in the Node Type Editor. Custom types can be built on either Node Type YAML or SQL.
UDNs let teams encode organization-specific patterns: naming conventions, incremental strategies, platform-specific DDL, and governance columns.
UDNs follow the same Deploy and Refresh lifecycle as default Nodes. Store definitions in version control and test in a Workspace before promoting to Environments.
