Snowflake Data Object Lookup Operation Properties

Snowflake Data Object Lookup Operation Properties

Snowflake data object lookup operation properties include run-time properties that apply to the Snowflake data object.
The Developer tool displays run-time properties for the Snowflake data object lookup operation in the Run-time view.
The following table describes the run-time properties for a Snowflake data object lookup operation:
Property
Description
Lookup caching enabled
Indicates whether the Data Integration Service caches lookup values.
Select
Lookup caching enabled
 to enable lookup caching. When you enable lookup caching, the 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 Integration Service issues a select statement to the lookup source for lookup values.
The Integration Service supports lookup caching on the native and non-native environments. The Integration Service does not support uncached lookup in the non-native environment.
The Developer tool displays advanced properties for the Snowflake data object lookup operation in the Advanced view.
The following table describes the advanced properties for a Snowflake data object read operation:
Property
Description
Database
Overrides the database name specified in the connection.
Schema
Overrides the schema name specified in the connection.
Warehouse
Overrides the Snowflake warehouse name specified in the connection.
Role
Overrides the Snowflake user role specified in the connection.
Pre SQL
SQL statement that the Data Integration Service executes before extracting data from the source. For example, if you want to update records in the database before you extract the records from the table, specify a pre-SQL statement.
Post SQL
SQL statement that the Data Integration Service executes after extracting data from the source. For example, if you want to delete some records after the latest records load, specify a post-SQL statement.
Table Name
Overrides the table name of the imported Snowflake source table.
