Concepts

The IIR Table Loader extracts data from either a flat-file or database tables and creates an Identity Table (IDT) and Identity Indexes (IDXs).

It is a multi-threaded application and performs the following tasks in parallel:

Reads input source (flat-file or database)

Generates keys (multiple threads)

Sorts and writes output files for DBMS mass load utilities

Runs DBMS mass load utilities (multiple threads)

The Loader takes checkpoints between phases in its processing and can be restarted after a failure.
