Cassandra is a distributed structured data storage solution (NoSql database), with a richer storage structure than Key-Value databases (like Redis), but has limited support than Document databases
Category: Load Balance
Load Balance is based on the existing network structure, and allocates requests to multiple operating units for execution, such as Web servers, FTP servers, enterprise key application servers, and other mission-critical servers, so as to complete work tasks together . It provides a cheap, effective and transparent way to expand the bandwidth of network devices and servers, increase throughput, strengthen network data processing capabilities, and improve network flexibility and availability.
Configuration and non-equivalent load balancing experiments of EIGRP protocol
eigrp protocol: From the perspective of packet encapsulation, EIGRP is encapsulated in the IP header. The protocol is a three-layer protocol and is a CISCO private protocol that supports load balan

EIGRP simple application
Experiment simple application of EIGRP1. Purpose of experiment
Through this experiment, you can:
1) master the basic configuration of EIGRP
2) understand EIGRP’s neighbor table , The meaning of the
Haproxy and MySQL Master-Master replication speed is extremely slow
I have two MySQL servers in multi-master mode with HAproxy machines for simple load balancing/redundancy. When I connect directly to one of the servers and try to update approximately At 100,000 en
