Wishing to contribute from multitenancy angle

iramkumar — Mon, 17 Nov 2014 12:03:37 GMT

I just published a paper on graphical financial risk modeling and used Activiti as the engine for experiments. I am very happy with Activiti and the ease of use, clean documentation and next generation concepts it has integrated.I wish to contribute to Activiti from a multi-tenancy standpoint that w

Can you share more details about the multi tenancy functionality you are thinking about?

Best regards,

Mult-tenancy refers to the ability to run tenants getting a single view of a code shared between multiple tenants. Extensibility is an important aspect in which Activiti can fit very well. It already has a tenantID when starting processes which have same definition or definitions with modifications.

At present, I am not all sure what are the things of any priority for Activiti. For example, can you pass QoS parameters into processes? Can you signal processes to slow down their speed of execution? Can you signal different persistence mechanisms to processes (There is work on NoSQL Activiti also) These are some vague ideas. If there are pointed extensions Activiti wants to do then I can take it forward.

My short paper on how I used Activiti is here.

How would that work, passing QoS parameters into processes? Could you give a practical example?
What would be the purpose of slowing down the speed of execution of a specific process instance?
Different persistence mechanisms would work for dynamically changing the history level for a specific process instance. The NoSQL Activiti work was just a prototype for now.
Thanks for sharing the paper. I'm still figuring out what kind of multi tenancy functionality you are thinking about.

Best regards,

For example I am in financial risk when a large number of rules of executed by a rule engine to give a final result on the amount of money to be held. If rule depth was a parameter we can give different answers that are approximate or exact to that extent. This could probably be passed as a hash map variable as it is done right now. But a framework would be even better.

What would be the purpose of slowing down the speed of execution of a specific process instance?
In Multi-tenancy, in methodology you allocate quotas to different clients. If some one exceeds the quota we slow them down.

I am only looking as of now to contribute to open areas. Even I am not very sure how to do the same.
