How to create and use a lookup catalog

Lookups defined in a graph are always available to the graph. A shared catalog is used when one graph creates and publishes lookups that other graphs can use.

m_catalog commands help to manage catalog file. 

Lookup Catalog files gives performance improvement in data processing. It separates reference data refresh from day-to-day data processing. 

Separating reference data refresh from main processing helps to avoid concurrency, dead locks with database.
