…ntion DuckDB 1.5.0: non-blocking checkpointing, free block reuse, 17% throughput improvement. Storage format v67→v68 upgrades transparently on first open. ArchiveService: compact per-cycle parquet files into monthly files (YYYYMM_tablename.parquet) after each archive cycle. Strips dead query_plan_text column from query_store_stats during compaction. Uses in-memory DuckDB connection — no contention with collectors. Reduces steady-state archive from thousands of files to ~75 (25 tables × 3 months). RetentionService: switch from 90-day file deletion to 3-month monthly file deletion. Recognizes all naming formats (YYYYMM_, YYYYMMDD_, YYYY-MM_). Benchmarked: v_wait_stats query dropped from 1.7s to 0.03s after compaction. Lite refresh stable at 1.3-1.5s (down from 6-13s pre-optimization).
