Re: [qvto-dev] How to improve QVTo performance

Hi,

Thank you, Ed for your response!


The QVTo project as a whole is in a slow transition from the Ecore-based to the Pivot-based OCL which provides a variety of caches, optimisations, code generation. These render many improvements to the current code base obsolete.

Can I apply one of these techniques, let's say: caching technique to the current code base to make QVTo faster? I am interested in how to improve the performance of the current engine. Do you also think: Would the data type effect the performance?
 

Additional contributors are very welcome, but we need to trade off the time spent mentoring a new contributor against the size and quality of the contributions. So if you interest is for only a few hours this week, ...

You are right. Since I am new to QVTo and wanted to learn QVTo, I need guidance from the community.  

With so much changing behind the scenes it is difficult to make a small contribution. Perhaps the most useful would be in the provision of better examples; currently there is just UML2RDBMS. A UML example with stereotypes is high on my wanted list. 
If you are interested in making a major contribution, perhaps 10 hours per week for a few months we can discuss what might interest you and integrate with other contributions.

I can work on QVTo about 20 hours/week from now to 11 December.   I am more interested in how to improve the current QVTo engine performance. And I can use the current test suites from QVTo to test the patches.

Have a nice weekend,

Kind regards,
Minh

I am new to QVTo. I would like to improve QVTo performance. I found one bug [1] in the bug list related to QVTo performance issue. Could you please give some guidance/suggestion on how to tackle this problem? It would be great if I could contribute something to QVTo code base.

Thank you,

Kind regards,
