When is cachemetadata called

Variable or any subclass thereof: These members are exposed to the runtime as public variables. Activity or any subclass thereof: These members are exposed to the runtime as public child activities.

The default behavior can be implemented explicitly by calling AddImportedChild , passing in the child activity. ActivityDelegate or any subclass thereof: These members are exposed to the runtime as public delegates. ICollection of type Variable : All elements in the collection are exposed to the runtime as public variables. ICollection of type Activity : All elements in the collection are exposed to the runtime as public children. ICollection of type ActivityDelegate : All elements in the collection are exposed to the runtime as public delegates.

The CacheMetadata for activities that derive from Activity , CodeActivity , and AsyncCodeActivity also function as above, except for the following differences:. Classes that derive from Activity cannot schedule child activities or delegates, so such members are exposed as imported children and delegates; the. Classes that derive from CodeActivity and AsyncCodeActivity do not support variables, children, or delegates, so only arguments will be exposed.

You should not expect the delta shown in profiling to completely match up with observed throughput. From the comparison report you can right-click on the method name and go to the function in the baseline and comparison reports. This will take you to the function view in those reports. By double-clicking the function name in the function view, you can see the Function Details view, which breaks down the costs for the method.

CacheMetadata calls System. This is obviously where we incur the performance cost for reflection. Most workflows will be bottlenecked at some other area like service calls or persistence so the real-world benefits are most likely going to be small.

WriteLine "Press enter to start" ; Console. Now; WorkflowInvoker. Now - startTime; Console. WriteLine ts. Activities; using System. In, true ; metadata. Therefore, it is best to rely on the in-memory caching for cases where metadata changes often.

When you are caching to a database : CacheMetadata can only be used with CacheLocation. If you are caching to another database with the CacheProvider and CacheConnection properties, use AutoCache to cache implicitly.

Cache Metadata This property determines whether or not to cache the table metadata to a file store. Data Type bool Default Value false Remarks As you execute queries with this property set, table metadata in the API catalog are cached to the file store specified by CacheLocation if set or the user's home directory otherwise.
