Using multiple policies inside apply_policies

Support Installation and Deployment

Suppose I gave multiple policies in a session object for a user, which one will be chosen? What is the criteria for it? How will be it applied?

"apply_policies": [
    "59672779fa4387000129507d",
    "53222349fa4387004324324e",
    "543534s9fa4387004324324d"
    ]

A policy is a template for a key and that key is what is used in the session. How a policy is chosen in the keys is determined by their partitions and the API being accessed. I have not tried but I assume you might get a weird behavior if you enable quota, acl and rate_limit for all the policies. Or it could just select one (probably the first) out of all the policies to enforce. Generally you want to abstain from setting a configuration that could cause unintended behaviors.

Hope this helps.
