multiple event handlers fifo grouping

We're looking at implementing FIFO grouping, but it may be complicated, and we're curious about combining more than one aspect of processing, thus our subject; multiple event handlers fifo grouping.

1) Is it possible or is it to be avoided?

2) Will the different handlers manage the fact that their grouping may not be based on the same fields as other handlers?

3) Will thread usage remain constant across different handlers; imagine we set max to 16, will handler1 always use the same amount?

thanks

Hi, There can be only one FG property per type. Please elaborate regarding the use case.

Regards, Ester.

Let's imagine I have an abstract base class, and the fifo grouping property is declared inside that class. I have a number of clients that derive from that class but that I wish to process separately, and therefore I want to have an individual handlers for each of those classes. Is there any problem with this approach.

Regards

John

This approach seems fine, each class will be handled separately.

Once you've sub-classed by FifoGroup, do you still need more processing (Threads) per fifo group?

Take the diagram above. Imagine we implement grouping in the abstract class 'C'. We wish the classes 'E' & 'F' and any other descendants it might have to use FIFO based on the grouping we have declared in 'C'. As to the question about threading, it was intended mostly as a 'what will your algorithm do in this case' type of question, asked so that we wouldn't have to infer its behavior based on our testing. Additionally we were curious as to whether it was even possible to have different grouping declared at the 'E'/'F' layer instead of at 'C', and yet use a template based on 'C'? The second aspect of the question concerns the basic approach. Has this been tried before, in production somewhere or even in a test, and if so were there any issues?
