enhance: pipeline sealed BM25 stats materialization - #30
Merged
Conversation
Merge sealed segment statistics as individual loads complete so lazy IDF materialization overlaps object storage reads with aggregation. Reuse immutable cache-owned statistics and adopt the first deserialized field value to avoid redundant full copies. Add coverage for pipelined consumption, limiter cancellation, lease cleanup, and shared cache statistics. Signed-off-by: sijie-ni-0214 <sijie.ni@zilliz.com>
