Lookup Cache

Lookup Cache

You can enable lookup cache for a Snowflake lookup operation. When you enable lookup caching, the Integration Service caches the lookup source and runs the query on all the rows in the cache. The
Run-time
 tab displays the
Lookup Caching Enabled
 property that the Data Integration Service uses to lookup data from a Snowflake table. Lookup caching is enabled by default.
When you do not configure lookup caching, the Integration Service queries every input row of the lookup source instead of building and querying the lookup cache. You can enable lookup caching for large lookup tables to improve the performance of the lookup operation.
