As you have no doubt read elsewhere, the Unique Constraints Server Extension for Tamino 4.1.4 has now been released.
It can be downloaded here:
The main difference with this release is performance. Special thanks must go to Gerald Petry and Jakub Manikowski for their patience and determination in testing the code. (Thank you both!)
The original release performed a query to check if the constraint definitions in a schema had changed. This check was performed for every insert/update, and effectively doubled the execution time of these operations.
The new release does not perform this check - leading to a significant improvement in performance. (There is now a new function to force the reloading of constraints, which can and should be called when the constraints are modified.)
