Feature Description: SA: whether the third party storage (e.g., database) is accessed in the current invocation Scope: Invocation Detail description: SA means whether the third party storage (e.g., Redis) is accessed in the current invocation. If the current invocation accesses the Redis, it may cause the multi-instance failure. For example, microservice instance A1 uses id "id1" to accesse the Redis and changes the id from "id1" to "id2". Then if microservice instance A2 still uses "id1" to accesse the Redis, it will be failed.
