| 释义 |
In computer programming, Database-as-IPC is an anti-pattern where a database is used as the message queue for routine interprocess communication in a situation where a lightweight IPC mechanism such as sockets would be more suitable. British computer scientist, Junade Ali, defined the Database-as-IPC Anti-Pattern as using a database to "schedule jobs or queue up tasks to be completed", noting that this anti-pattern centres around using a database for temporary messages instead of persistent data.[1] Using a database for this kind of message passing is extremely inefficient compared to other IPC methods and often introduces serious long-term maintenance issues, but this method enjoys a measure of popularity because the database operations are more widely understood than "proper" IPC mechanisms.[2] References1. ^{{cite book|last1=Ali|first1=Junade|title=Mastering PHP Design Patterns|date=September 2016|publisher=Packt Publishing Limited|location=Birmingham, England|isbn=978-1-78588-713-0|pages=45-46|url=https://www.packtpub.com/application-development/mastering-php-design-patterns|accessdate=11 December 2017}} {{compsci-stub}}2. ^[https://www.engineyard.com/blog/5-subtle-ways-youre-using-mysql-as-a-queue-and-why-itll-bite-you 5 subtle ways you’re using MySQL as a queue, and why it’ll bite you] Schwartz, Baron. 2011 September 14. 2 : Anti-patterns|Databases |
