Questions and Answers
What benefits does the parallel loading of requests have?
Several requests can be updated more quickly in the ODS object.
Can the loading of requests and their activation be started independently from one another?
Yes. For this, you can create a process chain that starts the activation process after the loading process.
Is there a limit on the number of records that can be simultaneously activated?
No.
Can the loading mode, for loading into the ODS object, be changed from full to delta?
Yes, but only if the selection conditions do not overlap.
Why is the change log larger than the table of active data after several data loads?
The change log grows in proportion to the table of active data, because before and after-images are saved here with each new request. See also the Example of Updating Data into an ODS Object and the description of the Delta Process
Can the change log data be deleted after activation?
If a delta initialization for the update exists in connected data targets, the requests have to be updated first before the respective data can be deleted in the change log. From the ODS object administration, you can then call up the function to delete the change log data. This can be scheduled to occur periodically.
However, you cannot immediately delete the data that was just activated, because you can only specify Older Than 1 Day as the most recent deletion selection.
Are locks set when deleting data from the ODS object so that simultaneously writing is not possible?
Yes. With the activation, loading, deletion, and archiving processes, locks are set so that these processes cannot run at the same time.
When is it useful to delete data from the ODS object?
There are three options available for deleting data from the ODS object: by request, selectively, and from the change log. In order to determine the most useful option, read the detailed description about deleting from the ODS object.
What benefits does the new maintenance of secondary indexes have?
The secondary indexes created in the maintenance of the ODS object can be transported. They can then be created in the development system and transported into the production system.
For what purpose is the transactional ODS object necessary?
For being able to load data quickly (without staging). See also the section Transactional ODS Objects.
