Data Node

DataNode is the component to write insert and delete messages into persistent blob storage, for example MinIO or S3.

Dependency

  • KV store: a kv store that persists messages into blob storage.
  • Message stream: receive messages and publish imformation
  • Root Coordinator: get the latest unique IDs.
  • Data Coordinator: get the flush information and which message stream to subscribe.
