As we know, metadata is stored in the memory of the EventMesh. When a large-scale cluster encounters jitters, both consistency and reliability are at risk. Here, we hope to propose a metadata management system based on raft or gossip protocol. The dledger, etcd, or jgroups component can be introduced. Welcome to sign up and get the task:-)
