James Wright: The Power of Promises and Parallel XQuery Execution

James Wright I will introduce simple library which implements the promise pattern as seen in many other languages and frameworks. Most notably those in the javascript community, such as jQuery, Q.js and even EMCAScript 6. The pattern resolves around the idea of deferred execution through what is called a deferred. When an action is deferred, it returns a function, known as a promise that when executed at a later time, will perform and return the results of the work it deferred. Since the work is deferred and can be executed at an arbitrary time. There is the ability to attach further processing at a later date but prior to actual execution, via callback functions. This may sound confusing and hard to imagine, but I ‘promise’ the examples that follow will make it clearer. No pun intended. slides: http://archive.xmlprague.cz/2016/file... http://www.xmlprague.cz/day3-2016/#pr...
