Why Milvus 3.0 Pagination Breaks After Reranking: When Cursor Scores Cross Worlds

Milvus 3.0's search iterator pagination fails after reranking because the cursor uses the last page's score as a boundary, but reranking replaces ANN distances with model predictions (e.g., XGBoost raw scores), causing the filter condition to exclude nothing and return duplicate pages. Milvus now explicitly rejects combining function chains with search iterators rather than fixing pagination, as the fix would require carrying original distances through the entire reduce pipeline—a feature-level change. Workarounds include using offset within single-search limits or moving reranking to the application layer.

Four States a Milvus Delete Passes Through – Uncovering the Most Complex Operation

A Milvus delete command looks simple, but the primary key is first stored in an L0 delta segment, then triggers compaction that merges the delete mark into L1/L2 segments, passes through four distinct segment states, and involves multiple seal strategies, rollback fields, and version‑specific behaviours, illustrating why deletion is the system's most intricate operation.
