enhance: Increase task capacity and clean illegal task (#37896)
1. taskQueueCapacity 256 is too small for production when we want to
re-write the entire collection

2. tasks should be cleaned when unable to recover, or the meta will
remain in etcd forever later.

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.
