In a JMS trigger service, can we pass the filter condition from config file?

I want the trigger filter to be: location=‘xyz’. The location value keep changing in time, so I want to fetch this value from config file. How to achieve this?

In UM, what are the maximum number of joins we can add in topic?

Reg. the trigger requirement, you cannot pass the filter condition from config file directly but you can create/update a trigger filter condition with the help of a java service or by WmRoot services by reading the config file and others props.

About the max number of joins, I do not think there is a hard limit on this.

Any questions?
