What is difference between async true/false on a relationship

When setting up a relationship in ember what is the difference between a async:true and async:false.

We ran into a problem where we had a computed property with a belongsTo property as the dependency and would findAll, then somehow it was getting caught in an infinite loop until we added async:true to the relationship. wondering why it would make a difference, and what async option actually affects. The docs don’t cover it very much

Hi,

Try to look in to below link. You will get some Idea.

Regarding your error, try to follow side loading for data.

Thanks.
