Decoupling API and ES index

I keep getting ES errors on the test server. Is there any reasonable expectation when we can decouple ES and the API? I find it a bit frustrating that I do an extreme effort to keep the API in a healthy condition (code wise / maintainability, etc) and that it relies on a crucial component that fails regularly.
