changes, never mutate existing ii. Remove application assumptions about DB version iii. The Canary & Cluster Immune System Release Patterns 1. Canary Strategy a. Automates the release process of promoting environments b. Successful application behavior moves to the next group; failure stops or rolls back 2. Cluster Immune Strategy a. Expands upon Canary. Links production monitoring with release process to automatically

Condi�on()方法创建一个条件对象， 条件对象能让一个进程A暂停下来，等待另一个进程B的通知，当进程B 满足某个条件后通知进程A继续运行 import multiprocessing def operator_func(cond, name): cond.acquire() print(name + ": 我可以变更了吗？") cond.notify() # 发消息给Manager，唤醒一个挂起的线程 变更方案有问题，先不变更，先改方案") cond.notify() # 发消息给Operator，唤醒一个挂起的线程 cond.wait() # 等待Operator的回复 print(name + ": 好，可以变更了") cond.notify() # 发消息给Operator，唤醒一个挂起的线程 cond.release() def main(): cond = multiprocessing.Condition() opuser = multiprocessing.Process(target=operator_func, args=(cond, "cof-lee",)) mgmt = multiprocessing.Process(target=manager_func, args=(cond, "boss",))
