History

enhance: Use partitionID when delete by partitionKey (#38231 )

When delete by partition_key, Milvus will generates L0 segments
globally. During L0 Compaction, those L0 segments will touch all
partitions collection wise. Due to the false-positive rate of segment
bloomfilters, L0 compactions will append false deltalogs to completed
irrelevant partitions, which causes *partition deletion amplification.

This PR uses partition_key to set targeted partitionID when producing
deleteMsgs into MsgStreams. This'll narrow down L0 segments scope to
partition level, and remove the false-positive influence
collection-wise.

However, due to DeleteMsg structure, we can only label one partition to
one deleteMsg, so this enhancement fails if user wants to delete over 2
partition_keys in one deletion.

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.
