System Tables

System tables make up Dremio's system-created catalog to store metadata for the objects in your Dremio organization. Each system table is specific to the associated Dremio object and its attributes, unlike Information Schemas, which are based on the ANSI standards. System tables are read-only (cannot be modified or dropped by users).


In Dremio 20+, the sys.dependencies table has been renamed to sys.reflection_dependencies.
