Connecting concurrent clients to your database may increase the load on the database server to a point where performance suffers as a result. We provide three configuration files as parameters. The configuration file is stored in Zookeeper Node data. The Couch Replication Protocol lets your data flow seamlessly between server clusters to mobile phones and web browsers, enabling a compelling offline-first user-experience while maintaining high performance and strong reliability.
