HI, CacheLoadOnlyStoreAdapter [1] perfectly fits for your cause it was deliberately designed for the cases when fast loading from raw files, CSV or other resources is needed.
Unfortunately there is no an example in Ignite that shows how to use this adapter for now. I've created a ticket to be sure that it will appear in the future. [2] Presently my suggestion is to refer to the following tests that can be used as a reference of CacheLoadOnlyStoreAdapter usage [3].
