How do I set up my project with no adapter type???

I saw a jira ticket @ the following link no persistence and would like to know how to set up my model to use no adapters....

For example I have the following in my model:

config: {
    columns: {
    },
    adapter: {
        type: "",
        collection_name: "Test_Applicant"
    }
},

"Couldn't find model: sync/localDefault"

Apparently it's possible to set up my models to use no adapter types but I can't seem to figure it out...any body know how?
