Tomcat 8 DeltaManager 与 BackupManager 会话复制
Tomcat 8 DeltaManager vs BackupManager session replication
我将使用安装了 Tomcat 8 的独立 AWS EC2 实例配置 2 个节点集群。
我需要配置 Tomcat 会话复制。
根据 Tomcat 8 文档 Clustering/Session Replication HOW-TO:
In this release of session replication, Tomcat can perform an all-to-all replication of session state using the DeltaManager or perform backup replication to only one node using the BackupManager. The all-to-all replication is an algorithm that is only efficient when the clusters are small. For larger clusters, to use a primary-secondary session replication where the session will only be stored at one backup server simply setup the BackupManager.
你能告诉我这是什么意思吗 - 集群很小？
是 2..5..100...1000 个节点还是什么？
