Data Coordinator

Data cooridnator(datacoord for short) is the component to organize DataNodes and segments allocations.

Dependency

  • KV store: a kv store has all the meta info datacoord needs to operate. (etcd)
  • Message stream: a message stream to communicate statistics information with data nodes. (Pulsar)
  • Root Coordinator: timestamp, id and meta source.
  • Data Node(s): could be an instance or a cluster, actual worker group handles data modification operations.
