Variant Extracts
Variants are a special type of extract, with less rigorous control of claiming elements and writing data back to the owning extract. They are designed to allow users to try out different designs, which then may or may not be written back to the master.
Variants are different from normal extracts (including Working extracts) in the following ways:
•
Any element can be modified without being claimed, and so different users can modify the same element in different variants.
•
When data is written back to the owning database, it will overwrite any conflicting data in the owner.
A variant can have normal extracts created from it. Note that in this case, the variant forms a new root for claiming elements: claims in extracts below the variant will not be visible from other parts of the extract family, and claims in other parts of the family will not be visible in extracts owned by the variant.
If a variant extract is owned by a normal extract, then data must be claimed to the owning extract when flushing from the Variant. This will be done as part of the Flush command from the Variant, and the Flush will fail if not all elements can be claimed.
It is possible to have working variants.
