and Analytics Spring 2020 2/11: Windows and Triggers Vasiliki (Vasia) Kalavri vkalavri@bu.edu ## Window operators • Practical way to perform operations on unbounded input • e.g. joins, holistic aggregates different things • last 5 sec • last 10 events • last 1h every 10 min • last user session ## Example: Window sensor readings object MaxSensorReadings { def main(args: Array[String]) { val env = = env.addSource(...) } } ### Keyed vs. non-keyed windows Window operators can be applied on a keyed or a non-keyed stream: • Window operators on keyed windows are evaluated in parallel • Non-keyed

有鉴于图形使用者接口（Graphical User Interface, GUI）的需求日益加重，在 1984 年由 MIT 与其它协力厂商首次发表了 X Window System，并且更在 1988 年成立了非营利性质的 XFree86 这个组织。所谓的 XFree86 其实是 X window system 与 Free 及 x86 系统架构的整合名称呢！而这个 XFree86 的 GUI 接口更在 Linux 的核心 Unix。不过，毕竟由 Torvalds 先生负责维护的 Linux 提供的仅是『核心』与『核心工具』的集合，对于需要更完整功能的操作系统来说，毕竟还不够完备，例如如果你要桌面程序，还得要加入 X-Window 系统对吧！？如果你要架设 WWW 还得加入服务器软件对吧？所以，虽然 Linux 的核心已经提供了相当多的支持与工具程序，但毕竟还不足以构成一个很完整的操作系统。 好在，由于 Linux 的稳定性良好，并且可以在便宜的 人会到府服务啦！不过，这点倒是不需要担心，因为拜网络风行之赐，你要问的问题几乎在网络上都可以找到答案喔！看你有没有用心去找就是了！ - 图形接口作的还不够好：其实是因为 VBird 不玩 X-window 啦，所以也不知道目前发展到怎样的一个地步了！基本上 VBird 常说的一句话就是：『Windows 上面有的咚咚 Linux 上面也一定可以找的到！，但 Linux 有的服务 Windows

close to its UNIX roots, Linux provided a Command Line Interface (CLI) first; the adaptation of the X Window System made a graphical user interface (GUI) available at a later stage. ![Image](/uploads/do for the desktop and working on the programmes which manage application launching, file handling and window and task management. Community members worldwide contribute to the translation and accessibility navigation between windows. For example, you might have the Firefox window, an OpenOffice application, a search window and a calculator window open on the desktop. ![Image](/uploads/documents/f/0/7/0/f070
