Subject: [PATCH 12/35] feat(31): wire TableConfig into sort path, add compaction KV metadata Wire TableConfig-driven sort order into ParquetWriter and add self-describing Parquet file metadata for compaction: - ParquetWriter::new() takes &TableConfig, resolves sort fields at construction via parse_sort_fields() + ParquetField::from_name() - sort_batch() uses resolved fields with per-column direction (ASC/DESC) - SS-1 debug_assert verification: re-sort and check identity permutation - build_compaction_key_value_metadata(): embeds sort_fields, window_start, window_duration, num_merge_ops, row_keys (base64) in Parquet kv_metadata - SS-5 verify_ss5_kv_consistency(): kv_metadata matches source struct - write_to_file_with_metadata() replaces write_to_file() - prepare_write() shared method for bytes and file paths - ParquetWriterConfig gains to_writer_properties_with_metadata() - ParquetSplitWriter passes TableConfig through - All callers in quickwit-indexing updated with TableConfig::default() - 23 storage tests pass including META-07 self-describing roundtrip Co-Authored-By: Claude Opus 4.6 (1M context) --- quickwit/Cargo.lock | 94 +--

charset=UTF-8 Content-Transfer-Encoding: 8bit Gap 1: Change window_duration_secs from i32 to Option in both PgMetricsSplit and InsertableMetricsSplit. Pre-Phase-31 splits now correctly map 0 → NULL in PostgreSQL, enabling Phase 32 compaction queries to use `WHERE window_duration_secs IS NOT NULL` instead of the fragile `WHERE window_duration_secs > 0`. Gap 2: Change zonemap_regexes from String to serde_json::Value in both structs. This maps directly to JSONB in sqlx, avoiding ambiguity when PostgreSQL JSONB operators are used in Phase 34/35 zonemap pruning. Gap 3: Add two missing tests: - test_insertable_from_metadata_with_compaction_fields: verifies all 6 compaction fields round-trip through InsertableMetricsSplit - test_insertable_from_metadata_pre_phase31_defaults: verifies pre-Phase-31 metadata produces window_duration_secs: None, zonemap_regexes: json!({}) Co-Authored-By: Claude Opus 4.6 (1M context) --- .../src/metastore/postgres/metastore.rs | 12 +-- .../src/split/postgres.rs | 79 ++++++++++++++++--- 2 files changed, 70 insertions(+), 21 deletions(-) diff --git a/quickwit/quickwit-metastore/src/metastore/postgres/metastore.rs b/quickwit/quickwit-metastore/src/metastore/postgres/metastore.rs index 49da0df7e12..11ad65c6753 100644 --- a/quickwit/quickwit-metastore/src/metastore/postgres/metastore.rs +++ b/quickwit/quickwit-metastore/src/metastore/postgres/metastore.rs @@ -1844,15 +1844,11 @@ impl MetastoreService for PostgresqlMetastore { size_bytes_list.push(insertable.size_bytes);

charset=UTF-8 Content-Transfer-Encoding: 8bit Extract duplicated invariant logic into a shared `invariants/` module within `quickwit-dst`. This is the "single source of truth" layer in the verification pyramid — used by stateright models, production debug_assert checks, and (future) Datadog metrics emission. Key changes: - `invariants/registry.rs`: InvariantId enum (20 variants) with Display - `invariants/window.rs`: shared window_start_secs(), is_valid_window_duration() - `invariants/sort.rs`: generic compare_with_null_ordering() for SS-2 - `invariants/check.rs`: check_invariant! macro wrapping debug_assert - stateright gated behind `model-checking` feature (optional dep) - quickwit-parquet-engine uses shared functions and check_invariant!
