Version upgrade of metaloaders gets difficult when customers change or add tools to already complex metaloader workflows.
Please better support customer customization by placing macros in the metaloaders at critical points
- just after data input
- just before data output
These macros would do nothing except pass data in and out
with the intent that customers build these out as they need to improve the resulting data catalog.
Most customer modifications could fit within limits of what these macros could do.
It would be easier to upgrade version when most often it only required replacing entire macros that had been modified.
The improvement would be worth the nominal impact on performance.
Where performance is a problem, un-customized macros could be removed.
