11.2.1 Data Loading MethodsConventional path load is the default method used by EDB*Loader. Basic insert processing is used to add rows to the table.The advantage of a conventional path load over the other methods is that table constraints and database objects defined on the table such as primary keys, not null constraints, check constraints, unique indexes, foreign key constraints, and triggers are enforced during a conventional path load.One exception is that Postgres Plus Advanced Server rules defined on the table are not enforced. EDB*Loader can load tables on which rules are defined, but the rules are not executed. As a consequence, partitioned tables implemented using rules cannot be loaded using EDB*Loader.Note: Postgres Plus Advanced Server rules are created by the CREATE RULE command. Postgres Plus Advanced Server rules are not the same database objects as rules and rule sets used in Oracle.EDB*Loader also supports direct path loads. A direct path load is faster than a conventional path load, but requires the removal of most types of constraints and triggers from the table. See Section 11.2.5 for information on direct path loads.
