// FailFast configures the action to take when an RPC is attempted on broken

// connections or unreachable servers. If failFast is true, the RPC will fail
// immediately. Otherwise, the RPC client will block the call until a
// connection is available (or the call is canceled or times out). Please refer
// to https://github.com/grpc/grpc/blob/master/doc/wait-for-ready.md.
// The default behavior of RPCs is to fail fast.
// connection is available (or the call is canceled or times out) and will
// retry the call if it fails due to a transient error. gRPC will not retry if
// data was written to the wire unless the server indicates it did not process
