When starting the app you first build your RDD and cache it. In your spray "endpoints" you will translate the HTTP requests to operations on that RDD. 2014-08-17 17:27 GMT+02:00 Zhanfeng Huo <huozhanf...@gmail.com>: Hi, All: I have a demand that using spark load business data daily and cache it as rdd or spark sql rdd. And other users can query base on it (in memery). As a summary, it requires that the app must runing as a deamon service that can last for one day at least and user's app can access it's rdd. How can I achieve this require ? Thanks. Zhanfeng Huo
