Hi All,
what are the maxiumum number of instances can we set for a message flow?
What is the ideal number of instances which we can set in live condition?
if there are 50 instances for a flow does it have any adverse affect?
Is there a command to know how many instances are set for a particular flow? without opening the flow?
Valid inputs plz |

Use one instance unless you know this to be insufficient.
Bear in mind the sequencing aspect of parallel processing, and the risk of database deadlocking.
Ideally flows should be designed so they can run in parallel, how it should not be assumed.
But it will depend on peak load, required throughput, elapsed time constraints etc. Sometimes a peak time backlog is not a problem and no need to have extra flow instances taking up memory etc.
One of the reasons people look at parallel processing is if the flow calls another service and waits for it to respond in line. This is actually not always a good way to code the logic. Waiting in flows should be avoided where possible. |
