Load balancing is an algorithm that is used to solve a machine (a process) that cannot resolve all requests.
The load Balancing Sink Processor can implement the

Application Scenarios for remote file synchronizationIn a load-balanced cluster scenario, there is often a load Balance Server on the front end of multiple Web servers that provides1 The client accesses a unified domain name to this
I haven't written a blog for a long time. We have recently studied storm, flume, and Kafka. Today, I will write down the scenarios and conclusions for testing flume failover and load balance;
The test environment contains five configuration files, that is, five agents.
A main configuration file, that is, the configuration file (flume-sink.properties) for configuring the Failover and
have been established through the least-connection scheduling algorithm. If the real server of the cluster system has similar system performance, the "Minimal connection" scheduling algorithm can be used to balance the load well.WLC weighted Minimum link (weighted least connections)In the case of the server performance difference in the cluster system, the scheduler uses the "Weighted least link" schedulin
nginx agent function and load balance detailed explanation
Preface
Nginx's agent function and load balancing function are most commonly used, about Nginx basic grammar and configuration has been explained in the previous article, this is to come to the point, first describe some of the configuration of the agent function, and then explain the
partitions Toolwhat does the tool do?The goal of this tool are similar to the referred Replica Leader election tool as to achieve load balance across brokers. But instead of electing a new leader from the assigned replicas of a partition, this tool allows to change the Assign Ed replicas of Partitions–remember that followers also need to fetch from leaders in order to keep in sync, hence Someti Me only
