Run-time Properties

Run-time Properties

Set the run-time properties to configure a cached or uncached lookup in a mapping.
When you enable lookup caching, the Data Integration Service caches the lookup values. The Data Integration Service queries the lookup source once, caches the values, and looks up values in the cache. Caching the lookup values can increase performance on large lookup tables. By default, the
Lookup caching enabled
 check box is selected.
When you disable caching, the Data Integration Service does not caches the lookup values. The Data Integration Service queries the lookup source instead of building and querying the lookup cache. Each time a row passes, the Data Integration Service issues a SELECT statement to the lookup source for lookup values. Do not select the
Lookup caching enabled
 check box to enable the uncached lookup.
