the certificates are persisted to disk, rather than kept in memory like in the standard Kubernetes deployment.

## Certificate Rotation

The agent also handles rotating certificates near expiration. It does so by triggering a callback from the `SecretManager` to the SDS server
when a certificate is near expiration (configurable by `SECRET_GRACE_PERIOD_RATIO`, defaulting to half of the expiration plus or minus a few minutes to stagger renewals). If the SDS server

@callback_router0.get("/")

callback_router1 = APIRouter()


@callback_router1.get("/")
async def callback1(level1: str):

### Asynchronous Get ([.kt][AsynchronousGetKotlin], [.java][AsynchronousGetJava])

Download a file on a worker thread, and get called back when the response is readable. The callback is made after the response headers are ready. Reading the response body may still block. OkHttp doesn't currently offer asynchronous APIs to receive a response body in parts.
