History

Ten Thousand Leaves a8e1c8fa9d

Make duplicate flush recalls success and other logic update (#16755 )

Latest logic:
1) Duplicate flush calls on same segments will not result in errors (same as the original design)
2) `FlushSegments` now still flushes stale segments even if non-stale segments failed to get flushed

issue: #16749

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.
