精彩书摘

　　《ErlangOTP可扩展性设计指南（影印版 英文版）》：
　　It's important to understandthe synchronous nature of start_link and its importance to a repeatable startupsequence.The ability to deterministically reproduce an error is important when trou—bleshooting issues that occur at startup.You could asynchronously start all of theprocesses， checking each afterward to make sure they all started correctly.But as aresult of changing scheduler implementations and configuration values running onmulti—core architectures， deploying to different hardware or operating systems， oreven the state of the network connectivity， the processes would not necessarily alwaysinitialize their state and complete the startup sequence in the same order.If all goeswell， you won't have an issue with the variability inherent in an asynchronous startupapproach， but if race conditions manifest themselves， trying to figure out what wentwrong and when， especially in production environments， is not for the faint of heart.The synchronous startup approach implemented in start link clearly ensuresthrough its simplicity that each process has started correctly before moving on to the next one， providing determinism and reproducible startup errors on a single node.
