Let's take a holistic look at the steps to build a storm cluster:
Setting up zookeeper clusters
Installation relies on all Nimbus and worker nodes
Download and unzip the storm release version to all Nimbus and worker nodes
Configure Storm.yaml
Start the related background process

This blog post details how to install the storm local development environment, which consists of two steps:
1. Download the storm release package from the official website, decompress the package, and add the decompressed bin directory to the environment variable (PATH, to facilitate subsequent execution of storm-related commands
2. Modify the

Storm and Kafka single-host functions are well integrated, but some problems occur in the storm Cluster Environment and data processing performance. The test process and problems are briefly recorded as follows:

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. The author's knowledge of storm usage scenarios such as real-time log analysis, real-time analysis of site user behavior, real-time computing, and so on, now many companies are also using
Storm 1.0. Version 0 adds a lot of new features, usability and performance improvements, which are a milestone version of Storm development, with the following key features.Performance improvementsStorm 1.0. The biggest highlight of the 0 version is the performance boost, which can be increased to 16 times times faster than the previous version, and the delay can be reduced to 60%. The topology performance
Storm is a distributed, open-source, real-time computing system that makes data flow processing simple and reliable, and therefore has a wide range of practical applications in big data.Application. Here's how to install Storm on a Linux system. According to Storm's official website, installing storm Software is five steps:
Install zookeeper.

ObjectiveDuring the previous period, I participated in the design of sentinel flow monitoring function, and researched two frameworks that can do flow calculation: Storm and spark streaming, I am in charge of Storm's research work. It took a week to read the doc on the official website and some information on the web. I summarize what I've learned into a document and issue it to get started with colleagues who are interested in storm.Storm backgroundW

Distributed RPC (distributed RPC,DRPC) is used to perform parallel computations on a large number of function calls on storm. For each function call, the topology running on the storm cluster receives the parameter information of the calling function as an input stream and emits the result of the calculation as an output stream.
DRPC itself is not a feature of storm
