This is another way to manage queues and worker clusters. Storm can also be used for "continuous computing" (continuous computation), which make

Original address The idea of real-time business intelligence is no longer a novelty (a page on this concept appeared in Wikipedia in 2006). However, although people have been discussing such schemes for many years, I have found that many companies have not actually planned out a clear development idea or even realized the great benefits. Why is that? One big reason is that real-time business intelligence and analytics tools are still very limited on the market today. Traditional Data Warehouse e

latency of 10 seconds is normal in large-scale statistics, but the fluctuation is obvious in seconds; If the heap is too small, woker is forcibly killed. Therefore, you must configure the-Xmx parameter; Custom items Static resources: static resource filtering options. You can use Content-Type or suffix to filter specific static resources.

Apache Storm is an open-source big data processing system by Twitter, and unlike other systems, Storm is designed for distributed real-time processing and language-independent.
