📄 Description

Description

Calling collection.flush() after every upsert creates severe performance bottlenecks and causes 'Rate limit exceeded' errors on standard Milvus configurations. It also leads to the 'small file problem' in MinIO/S3 and puts unnecessary load on etcd. Milvus handles persistence automatically via WAL and auto-flush policies. Removing manual flush allows Milvus to manage segments more efficiently.
