Result Set Cache Manager

Result Set Cache Manager

The Result Set Cache Manager manages cached results for SQL data service queries and web service requests. A result set cache is the result of a DTM instance that runs an SQL query against an SQL data service or a web service request against a web service operation.
When you enable result set caching, the Result Set Cache Manager creates in-memory caches to temporarily store the results of a DTM instance. If the Result Set Cache Manager requires more space than allocated, it stores the data in cache files. The Result Set Cache Manager caches the results for a specified time period. When an external client makes the same request before the cache expires, the Result Set Cache Manager returns the cached results. If a cache does not exist or has expired, the Data Integration Service starts a DTM instance to process the request and then it stores the cached the results.
When the Result Set Cache Manager stores the results by user, the Data Integration Service only returns cached results to the user that ran the SQL query or sent the web service request. The Result Set Cache Manager stores the result set cache for SQL data services by user. The Result Set Cache Manager stores the result set cache for web services by user when the web service uses WS-Security. The Result Set Cache Manager stores the cache by the user name that is provided in the username token of the web service request.
