Enterprise and Eon Database Modes
You can create a Vertica database in one of two modes: Enterprise Mode or Eon Mode. These modes control how and where the database stores its data. Each mode has its own distinct advantages. For more about these modes, see Vertica Architecture: Eon Versus Enterprise Mode.
You can migrate an Enterprise Mode database to Eon with the meta-function MIGRATE_ENTERPRISE_TO_EON. For details on using this meta-function, see Migrating an Enterprise Database to Eon Mode.
