METHOD AND SYSTEM OF SELF-MANAGING NODES OF A DISTRIBUTED DATABASE CLUSTER WITH A CONSENSUS ALGORITHM

机译:共识算法的分布式数据库集群自管理节点的方法和系统

摘要

In one exemplary aspect, a method of a distributed database system includes the step of detecting that a database node departed from a database cluster. A consensus-based voting process is implemented utilizing all of a set of other database nodes remaining in the database cluster. A cluster configuration is determined with the consensus-based voting process. The cluster configuration includes a new list of the set of other database nodes remaining, in the database cluster. The data is automatically rebalanced among the set of other database nodes remaining in the database cluster according to the cluster configuration. Optionally, the consensus-based voting process can include a Paxos algorithm. The database cluster can be a Not-Only SQL (NOSQL) distributed database cluster.
