Logical Data Object/Virtual Table Cache Properties

Logical Data Object/Virtual Table Cache Properties

The following table describes the data object and virtual table cache properties:
Property
Description
Cache Removal Time
The number of milliseconds that the Data Integration Service waits before cleaning up cache storage after a refresh. Default is 3,600,000.
Cache Connection
The database connection name for the database that stores the data object cache. Select a valid connection object name.
Maximum Concurrent Refresh Requests
Maximum number of cache refreshes that can occur at the same time. Limit the concurrent cache refreshes to maintain system resources.
Enable Nested LDO Cache
Indicates that the Data Integration Service can use cache data for a logical data object used as a source or a lookup in another logical data object during a cache refresh. If false, the Data Integration Service accesses the source resources even if you enabled caching for the logical data object used as a source or a lookup.
For example, logical data object LDO3 joins data from logical data objects LDO1 and LDO2. A developer creates a mapping that uses LDO3 as the input and includes the mapping in an application. You enable caching for LDO1, LDO2, and LDO3. If you enable nested logical data object caching, the Data Integration Service uses cache data for LDO1 and LDO2 when it refreshes the cache table for LDO3. If you do not enable nested logical data object caching, the Data Integration Service accesses the source resources for LDO1 and LDO2 when it refreshes the cache table for LDO3.
Default is False.
