Re: storm use case in sensor data

If the data is emitted in terms of streams continuously from a sensor then Storm would be the ideal framework to process the data. Storm infact lets you process streams of data in real time. To get brief overview go through documentation over storm. https://storm.incubator.apache.org/ On Thu,

Hi, Below are my inline comments: Does Apache storm supports cluster environment. If yes, does it supports load balancing as well? Yes, storm can be deployed in cluster environment. It supports load balancing too by distributing the task over cluster nodes. Is there any dependancy

Re: duplicated result

Hi, The issue lies with the number of tasks/executors specified for spout. Try specifying 1 spout and see if you could see duplicates. I suppose there would be no duplicates in specifying 1 spout and 1 exclamtion bolt. On Tue, May 6, 2014 at 5:23 PM, Bilal Al Fartakh

Re: Topology Suggestion Required for Batching

Hi, You can define spouts and bolts in such a way that, input streams read by spouts would be grouped on specified fields and these could be processed by specific bolts. This way, you could make batches of input stream. On Tue, May 6, 2014 at 11:02 AM, Kiran Kumar

Re: storm

you can see the output either in storm ui or in worker logs. As you have installed storm, download storm-starter project ( https://github.com/nathanmarz/storm-starter) and run the wordcount topology using maven compiler. On Thu, Jan 2, 2014 at 3:58 PM, James Xu xumingmi...@gmail.com wrote:
