Hello,I work for the Atos company. We use BPMN for our payment applications.Among all our BPMN models we have "transaction processing" model types. These models do not require any human intervention and we want them to be as fast as possible. So no human task in it.I made quite some tests on the Act

Hi,

What kind of transaction handling is implemented in the //J tool to overcome the limitations of the DB?
Do you mean it would be feasible to integrate //J in Activiti?

Best regards,

Hello,

We don't have transaction mechanisms. Or I would say : there will be a transaction mechanism for loops only. That's why it is so fast.

Also : the model and links are not read from the DB. Everything is in the generated Java code.

Of course such a behavior is useful when we have Service Tasks only, no human tasks.

So it's faster because we almost don't use the DB, everything is in the Java code. And we can configure threads the way we want.

As far as we are concerned, we consider using //J as the engine for such kind of processes. We have a prototype actually working : we generate //J diagrams from Activi diagrams.

Hi,

What kind of database did you use for your tests ? Have you tried Activiti with in memory DB ?

Best regards,
