The bulk update for attributes is specialized on easy to handle, high-performance updates in cases where binary content attachments can be ignored and need not be updated. In contrast to the standard update operation (chapter Import and update), the following applies:
-
A single control file “update.xml” is used (instead of one meta.xml file for each item to update).
-
A new document revision is always created with any attribute update operation.
-
Only the current revision of a document can be updated.
-
Only the attribute modification operations “updateAttributes” and “clearAttributes” are supported.
-
If no document to be updated is found, this is considered as an error (in the protocol file).1
The operations are based on the dedicated Integration Service method “alterMultipleAttributes” but otherwise they are similar to a classic update operation, e.g. in terms of the definition in the control file and concerning the file system structure, which is similar to the delete and export use cases that rely on only one XML control file.
