enhance: Set segment.maxSize param to 1024M (#30139)
issue: #25639 
/kind improvement

When the number of vector columns increases, the number of rows per
segment will decrease. In order to reduce the impact on vector indexing
performance, it is necessary to increase the segment max limit.

If a collection has multiple vector fields with memory and disk indices
on different vector fields, the size limit after segment compaction is
the minimum of segment.maxSize and segment.diskSegmentMaxSize.

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.
