How to make sure JPA Consumer just call once

[Imran Raza Khan]

I am refactoring legacy project and in which i have to read table which has
some meta data on the base of it i have to start activemq listeners.

Now i want to read this tables only once at the start of application how i
can make sure that jpa consumer just get called once

 from("jpa:my.imran.TopicMapping"
                +
"?consumer.namedQuery=select_topic_mapping&delay=5s&consumeDelete=false")
        .to("log:my?showAll=true&multiline=true");

I know we can use @consume but in my scenario it will not work as if i have
to restart application it should re read these records from table.

So how we can make sure to call JPA consumer only once in lifecycle of
application.
