Hi, I have the difficulty with the resource aware scheduler from the version 1.1.1. As suggested by the website, I add the following lines to storm.yaml: *storm.scheduler: “org.apache.storm.scheduler.resource.ResourceAwareScheduler”* * supervisor.memory.capacity.mb: 2048.0* * supervisor.cpu.cap

Apache Storm High Messaging Delay When Passing 5MB Images

2018-01-31 Thread Wuyang Zhang
I am playing with Apache Storm for a real-time image processing application which requires ultra low latency. In the topology definition, a single spout will emit raw images(5MB) in every 1s and a few bolts will process them. The processing latency of each bolt is acceptable and the overall computi
