Re: [akka-user] akka scheduler with long delays
Hello Greg, This question is basically the same as last week: https://groups.google.com/forum/#!topicsearchin/akka-user/combining$20Akka$20Persistence$20with$20Akka$20Scheduling/akka-user/CLRF6LP2G18 Suggestions have not changed since then :-) Try akka-quartz-scheduler or write a large scheduling system on your own. Not liking quartz shouldn’t really be the reason of avoiding a library that solves the problem you need to be solved… :-) — k On 28 July 2014 at 04:05:55, Greg Flanagan (ventis...@gmail.com) wrote: I'm building a reporting backend where users can schedule a report to be run weeks / months in advanced.

Re: [akka-user] akka scheduler with long delays
you're right, my dislike for quartz should cloud my judgement. sorry for the double post :) On Monday, July 28, 2014 3:59:02 AM UTC-7, Konrad Malawski wrote: Hello Greg, This question is basically the same as last week: https://groups.google.com/forum/#!topicsearchin/akka-user/combining$20Akka$20Persistence$20with$20Akka$20Scheduling/akka-user/CLRF6LP2G18 Suggestions have not changed since then :-) Try akka-quartz-scheduler or write a large scheduling system on your own.

[akka-user] akka scheduler with long delays
I'm building a reporting backend where users can schedule a report to be run weeks / months in advanced.
