## Purpose Avoid unnecessary IVF-PQ distance computation when a RowId filter selects only a subset of candidates in an inverted list. ## Changes - precompute matching code positions for each probed inverted list - scan only matching PQ codes when the filter is selective - retain the existing full-list fast-scan path when the filter is dense - apply the optimization to 4-bit, transposed, batched, and reader-backed search paths - keep the public API and search result semantics unchanged ## Tests ```text cargo fmt --all -- --check cargo clippy -p paimon-vindex-core --lib -- -D warnings cargo test -p paimon-vindex-core --lib ivfpq ``` The IVF-PQ test suite passes with 34 tests. -- This is an automated message from the Apache Git Service.
