Run-time Properties

Run-time Properties

Set the run-time properties to enable and configure lookup caching. You must add the Lookup transformation to a mapping before you can configure run-time lookup properties.
Select the
Lookup caching enabled
 check box to indicate whether the Data Integration Service must cache lookup values.
When you enable lookup caching, 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.
When you disable caching, each time a row passes into the transformation, the Data Integration Service issues a SELECT statement to the lookup source for lookup values.
