From 395e36463342c9c9153d62858759030f2d40c4b5 Mon Sep 17 00:00:00 2001 From: Esteban Zimanyi Date: Thu, 21 May 2026 07:59:46 +0200 Subject: [PATCH 1/8] =?UTF-8?q?feat(berlinmod):=20scaffold=20the=20full=20?= =?UTF-8?q?BerlinMOD-9=20=C3=97=203-form=20parity=20matrix=20on=20NebulaSt?= =?UTF-8?q?ream=20(33=20YAMLs,=2027/27=20cells)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Additive scaffold for the BerlinMOD-9 × 3 streaming-form parity contract on MobilityNebula, sibling to the existing SNCB Q-series and matching the MobilityFlink #3 / MobilityKafka #1 streaming-form definitions. All 27 cells covered: Q1 'which vehicles have appeared' — full (continuous + windowed + snapshot) Q2 'where is vehicle X at time T' — full Q3 'vehicles within 5 km of P' — full Q4 'vehicles inside region R (polygon)'— full Q5 'pairs of vehicles meeting near P' — partial (emit per-vehicle trajectories near P; consumer joins) Q6 'cumulative distance per vehicle' — partial (emit TEMPORAL_SEQUENCE; consumer computes length) Q7 'first passage of vehicle through POI' × {POI1, POI2, POI3} — full (per-POI fan-out) Q8 'vehicles within d of LINESTRING' — full (edwithin_tgeo_geo with LINESTRING geometry) Q9 'distance between X and Y at time T'— partial (emit X and Y trajectories; consumer joins) 18 of 27 cells are FULL (the BerlinMOD-Q semantic is computed entirely inside NebulaStream). 9 cells are PARTIAL — NebulaStream emits the per-window inputs (trajectory, candidate vehicles) and a consumer post-processes for the final BerlinMOD-Q answer. The partial pattern is the natural expression of these queries in NebulaStream's current SQL surface; the path to FULL is documented per-Q in docs/berlinmod-streaming-forms.md (a stream-self-join for Q5/Q9, a temporal_length scalar function for Q6). Form mapping to NebulaStream windows: continuous: SLIDING(time_utc, SIZE 1 SEC, ADVANCE BY 1 SEC) windowed: TUMBLING(time_utc, SIZE 10 SEC) snapshot: TUMBLING(time_utc, SIZE 5 SEC) MEOS-side surface consumed (already exposed by PR #14 + follow-ups): edwithin_tgeo_geo — Q3 (POINT predicate), Q4 (POLYGON, d=0.0), Q5 (POINT predicate), Q7 (per-POI POINT), Q8 (LINESTRING predicate) TEMPORAL_SEQUENCE — Q2 / Q5 / Q6 / Q9 (per-window per-vehicle trajectory) No new MEOS PhysicalFunction classes added; no C++ changes; no SNCB Q-series modifications. All 33 YAMLs are additive in a new Queries/berlinmod/ subdirectory. Add (additions): Queries/berlinmod/q1_{continuous,windowed,snapshot}.yaml (3) Queries/berlinmod/q2_{continuous,windowed,snapshot}.yaml (3) Queries/berlinmod/q3_{continuous,windowed,snapshot}.yaml (3) Queries/berlinmod/q4_{continuous,windowed,snapshot}.yaml (3) Queries/berlinmod/q5_{continuous,windowed,snapshot}.yaml (3, partial) Queries/berlinmod/q6_{continuous,windowed,snapshot}.yaml (3, partial) Queries/berlinmod/q7_poi{1,2,3}_{continuous,windowed,snapshot}.yaml (9, full via fan-out) Queries/berlinmod/q8_{continuous,windowed,snapshot}.yaml (3, LINESTRING predicate) Queries/berlinmod/q9_{continuous,windowed,snapshot}.yaml (3, partial) Input/input_berlinmod.csv (sample data: 3 vehicles × 21 events, 14 simulated seconds) docs/berlinmod-streaming-forms.md Validation: every YAML parses cleanly via python3 yaml.safe_load. Runtime verification gated on the NebulaStream test harness. Coverage: 27 of 27 cells (100 %), with 18 FULL and 9 PARTIAL annotated explicitly per Q. Path to FULL for the 9 PARTIAL cells is one MobilityNebula C++ PhysicalFunction class each (or a NebulaStream upstream stream-self-join), documented in docs/berlinmod-streaming-forms.md. ---

From 81f428c3e86ecfeb125d8b58b949e4c76ce5e7d8 Mon Sep 17 00:00:00 2001 From: Esteban Zimanyi Date: Thu, 21 May 2026 09:11:39 +0200 Subject: [PATCH 2/8] feat(meos): TEMPORAL_LENGTH aggregation closes BerlinMOD-Q6 streaming-form cells to full Adds the TEMPORAL_LENGTH aggregation across the four levels of the NebulaStream pipeline (logical / physical / parser / lowering) so the BerlinMOD-Q6 "cumulative distance per vehicle" streaming-form cells (continuous + windowed + snapshot) compute the spheroidal trajectory length entirely inside NebulaStream instead of emitting raw trajectories for a consumer-side reduction. Logical: nes-logical-operators/{include,src}/Operators/Windows/Aggregations/Meos/TemporalLengthAggregationLogicalFunction.{hpp,cpp} mirroring TemporalSequenceAggregationLogicalFunctionV2 but with finalAggregateStampType = FLOAT64. Registers as "TemporalLength" in the aggregation registry. Serializes through the existing TemporalAggregationSerde wire shape with the type tag overridden. Physical: nes-physical-operators/{include,src}/Aggregation/Function/Meos/TemporalLengthAggregationPhysicalFunction.{hpp,cpp} identical lift / combine / reset / cleanup to TemporalSequenceAggregationPhysicalFunction; the lower() path builds the same MEOS instant-set trajectory string, parses it via MEOSWrapper::parseTemporalPoint, and calls MEOS' tpoint_length(Temporal*) to return a single FLOAT64 result. Parser: nes-sql-parser/AntlrSQL.g4 adds the TEMPORAL_LENGTH lexer token and includes it in functionName. AntlrSQLQueryPlanCreator.cpp adds the TEMPORAL_LENGTH dispatch in both the case-label and string-name paths, parallel to TEMPORAL_SEQUENCE. Lowering: nes-query-optimizer/src/RewriteRules/LowerToPhysical/LowerToPhysicalWindowedAggregation.cpp adds the TEMPORAL_LENGTH special-case lowering, parallel to TEMPORAL_SEQUENCE, producing a TemporalLengthAggregationPhysicalFunction with the same (lon, lat, timestamp) state schema. YAMLs: Queries/berlinmod/q6_{continuous,windowed,snapshot}.yaml updated to call TEMPORAL_LENGTH directly; the FLOAT64 output column replaces the VARSIZED trajectory output; header comments updated to "FULL". Docs: docs/berlinmod-streaming-forms.md updated to reflect 21 cells full + 6 cells partial (Q5 + Q9 only); the path-to-full table now lists those two queries only. YAML safe_load green on all 3 Q6 cells. Build verification gated on the user's NebulaStream test harness (vcpkg-bootstrapped); the C++ code follows the established TemporalSequence template exactly, with the lower() path replaced by tpoint_length. --- Queries/berlinmod/q6_continuous.yaml | 20 +- Queries/berlinmod/q6_snapshot.yaml | 21 +- Queries/berlinmod/q6_windowed.yaml | 20 +- docs/berlinmod-streaming-forms.md | 29 +- ...mporalLengthAggregationLogicalFunction.hpp | 64 +++++ .../Windows/Aggregations/Meos/CMakeLists.txt | 1 + ...mporalLengthAggregationLogicalFunction.cpp | 117 ++++++++ ...poralLengthAggregationPhysicalFunction.hpp | 73 +++++ .../Aggregation/Function/Meos/CMakeLists.txt | 1 + ...poralLengthAggregationPhysicalFunction.cpp | 271 ++++++++++++++++++ .../LowerToPhysicalWindowedAggregation.cpp | 31 ++ nes-sql-parser/AntlrSQL.g4 | 3 +- .../src/AntlrSQLQueryPlanCreator.cpp | 47 ++- 13 files changed, 652 insertions(+), 46 deletions(-) create mode 100644 nes-logical-operators/include/Operators/Windows/Aggregations/Meos/TemporalLengthAggregationLogicalFunction.hpp create mode 100644 nes-logical-operators/src/Operators/Windows/Aggregations/Meos/TemporalLengthAggregationLogicalFunction.cpp create mode 100644 nes-physical-operators/include/Aggregation/Function/Meos/TemporalLengthAggregationPhysicalFunction.hpp create mode 100644 nes-physical-operators/src/Aggregation/Function/Meos/TemporalLengthAggregationPhysicalFunction.cpp diff --git a/Queries/berlinmod/q6_continuous.yaml b/Queries/berlinmod/q6_continuous.yaml index 036e9bb6b6..7b13911408 100644 --- a/Queries/berlinmod/q6_continuous.yaml +++ b/Queries/berlinmod/q6_continuous.yaml @@ -1,14 +1,14 @@ -# BerlinMOD-Q6 — continuous form (PARTIAL) -# "Cumulative distance travelled per vehicle."

Lower picks each vehicle's latest known position in the window, enumerates pairs (a < b), calls MEOS' geog_dwithin with dMeet = 200 m hardcoded for the BerlinMOD scaffold, and emits a string-encoded list of meeting pairs (vid_a, vid_b, ts, "<=dMeet" tag). Future PR can parameterize dMeet via a constant input. Closes Q5 × 3 cells. CROSS_DISTANCE(lon, lat, ts, vehicle_id) -> FLOAT64 Same lift shape. Lower picks the latest known position of each of the two target vehicles (VID_A = 100, VID_B = 200 hardcoded), drives the MEOS nad_tgeo_tgeo distance, and returns a FLOAT64 (NaN if either vehicle is unobserved). Future PR can parameterize (VID_A, VID_B). Closes Q9 × 3 cells.

But the section 'Not covered (15 cells / 5 queries)' at line 77 was a remnant from the pre-#16/#17 state and contradicts the rest of the doc. Remove it. Add a new 'Streaming-semantics tier overlay' section that classifies each BerlinMOD-Q by its streaming-execution tier (stateless / bounded-state / windowed / cross-stream) per the closed 7-value vocabulary proposed for the MEOS-API objectModel.streamingSemantics facet (see the sibling RFC on MEOS-API PR #10). The mapping makes the cross-binding picture explicit: a Q's tier on NebulaStream is the same tier on Flink / Kafka, and the table points to the equivalent generic wiring class on Flink for each tier. Two short follow-up notes explain why cross-stream looks different on NebulaStream (single-aggregation Cartesian enumeration vs Flink's interval-join across two streams — same semantic, different topology) and why Q7 is bounded-state rather than windowed (per-POI fan-out, per-(vehicle, POI) bounded state, no full-sequence reduction needed). Refresh the 'Sibling parity references' section to point at the current state of the Flink and Kafka work — Flink's per-tier wiring infrastructure under org.mobilitydb.flink.meos.wirings (5 generic classes covering 100% of the streamable surface) and Kafka's codegen mirror under org.mobilitydb.kafka.meos.

It's classified bounded-state here because the NebulaStream scaffold expresses it as a per-POI fan-out (one YAML per POI), each YAML computing the per-vehicle latest-known position predicate and selecting the per-(vehicle, POI) earliest qualifying timestamp inside the window. The state per (vehicle, POI) is bounded; no per-window reduction across the full sequence is needed. ## Sibling parity references -- **MobilityFlink #3** — same nine queries × three forms via Flink Java code, 27/27 cells, pure-Java predicates with `TODO(meos)` markers for future JMEOS bridges. -- **MobilityKafka #1** — same nine queries × three forms via Kafka-Streams Processor API, 27/27 cells, same pure-Java predicates. -- **MobilityDB-BerlinMOD** open PRs (#29/#27/#26/#24/#23) — batch BerlinMOD-9 cross-platform reports; the snapshot form converges to those outputs as the watermark advances. +- **MobilityFlink** — same nine queries × three forms on Flink.

This PR lands that future work: PAIR_MEETING now takes a fifth argument — a numeric constant in metres — and the physical operator uses it per-query. ## Surface PAIR_MEETING(lon, lat, ts, vehicle_id, dMeet) ^^^^^ new fifth arg (numeric constant, metres) The first four args remain FieldAccess (lon, lat, ts, vehicle_id); the fifth is pulled from the parser's constantBuilder as a numeric literal, parsed via std::stod, and threaded through the logical→physical lowering chain into the lower() lambda alongside the existing state pointers. ## Files (9, all stacked on #18 → #17 → #16 → #15) | Layer | File | |---|---| | Physical .hpp | PairMeetingAggregationPhysicalFunction.hpp — `DMEET_METRES` constexpr → `DEFAULT_DMEET_METRES` + instance field `dMeetMetres` | | Physical .cpp | PairMeetingAggregationPhysicalFunction.cpp — constructor takes dMeet; lower() passes it to the captureless lambda via `nautilus::val` | | Logical .hpp | PairMeetingAggregationLogicalFunction.hpp — constructor + create() factory take dMeet; getter `getDMeetMetres()` | | Logical .cpp | PairMeetingAggregationLogicalFunction.cpp — initialize field; Registrar deserialize path uses DEFAULT_DMEET_METRES (see Serde caveat below) | | Parser | AntlrSQLQueryPlanCreator.cpp — both PAIR_MEETING dispatch sites (lexer-token case + funcName string-name case) extract the constant from constantBuilder, std::stod it, pass to create() | | Lowering | LowerToPhysicalWindowedAggregation.cpp — pmDescriptor->getDMeetMetres() flows to the physical constructor | | YAMLs (×3) | Queries/berlinmod/q5_continuous.yaml, q5_snapshot.yaml, q5_windowed.yaml — add `, 200.0` as the explicit fifth arg; comments updated to reflect the parameterization | ## Serde round-trip caveat (out of scope for this PR) `AggregationLogicalFunctionRegistryArguments` is strongly typed to `vector` — there is no slot for a numeric constant in the existing Registrar interface, and `SerializableAggregationFunction` has no proto field for it either. As a result: - The parser path (live query execution) is FULLY parameterized — dMeet flows from SQL to physical correctly. - The Serde deserialize path falls back to DEFAULT_DMEET_METRES (preserves the 200 m scaffold behaviour). Round-trip fidelity for the dMeet value requires (a) adding a new field to SerializableAggregationFunction.proto, (b) extending AggregationLogicalFunctionRegistryArguments to carry it, and (c) threading both through Serialize/Register. That's an infrastructure change touching every registered aggregation; tracked as a follow-up. ## Build / test verification Cannot compile-verify locally — NebulaStream needs the full C++23 + vcpkg toolchain. Submitted for maintainer build verification (cc @marianaGarcez). Expected to compile cleanly; the only construction-time behaviour change is the constructor signature (5 params → 6 params for physical, 5 → 6 for logical create/ctor); the only runtime behaviour change is that dMeet is now read from the instance field instead of the class constexpr (the lambda receives it via the nautilus::val extra arg). ## Mirrors the CROSS_DISTANCE shape CROSS_DISTANCE (also added by #17, hardcoded VID_A=100, VID_B=200) has the exact same parameterization pattern; a sibling PR can apply the same change with (lon, lat, ts, vid, vid_a, vid_b) — 6 args total instead of 5.

The aggregation (added in #17) hardcoded the target vehicle pair at (100, 200) via static constexpr VID_A / VID_B, with the PR body noting parameterization as future work. This PR lands that future work: CROSS_DISTANCE now takes two unsigned- integer constants as its fifth and sixth arguments, and the physical operator uses them per-query. ## Surface CROSS_DISTANCE(lon, lat, ts, vehicle_id, vidA, vidB) ^^^^ ^^^^ new constants (uint64) The first four args remain FieldAccess; vidA and vidB are pulled from the parser's constantBuilder (two unsigned-integer literals), std::stoull them, and threaded through the logical→physical lowering chain into the lower() lambda alongside the existing state pointer. ## Files (9, same shape as PR #19's PAIR_MEETING change) | Layer | File | |---|---| | Physical .hpp | CrossDistanceAggregationPhysicalFunction.hpp — `VID_A/B` constexpr → `DEFAULT_VID_A/B` + instance fields `vidA/B` | | Physical .cpp | CrossDistanceAggregationPhysicalFunction.cpp — constructor takes both; lift-time lambda gets them via `nautilus::val` | | Logical .hpp | CrossDistanceAggregationLogicalFunction.hpp — constructor + create() factory + getters | | Logical .cpp | CrossDistanceAggregationLogicalFunction.cpp — initialize fields; Registrar deserialize falls back to defaults | | Parser | AntlrSQLQueryPlanCreator.cpp — both CROSS_DISTANCE dispatch sites extract two constants, std::stoull both, pass to create() | | Lowering | LowerToPhysicalWindowedAggregation.cpp — cdDescriptor->getVidA()/getVidB() flow to physical constructor | | YAMLs (×3) | Queries/berlinmod/q9_continuous.yaml, q9_snapshot.yaml, q9_windowed.yaml — add `, 100, 200` as explicit constants; comments updated | ## Serde round-trip caveat (same as PR #19) `AggregationLogicalFunctionRegistryArguments` is strongly typed to `vector` — no slot for integer constants. `SerializableAggregationFunction.proto` has no field for them. So: - Parser path (live query execution) is FULLY parameterized. - Serde deserialize path falls back to `DEFAULT_VID_A` / `DEFAULT_VID_B` (preserves the 100, 200 scaffold defaults). Same infrastructure follow-up would close both round-trip gaps at once (PAIR_MEETING.dMeet and CROSS_DISTANCE.vidA/vidB). ## Build / test verification Same as PR #19 — submitted for maintainer build verification (@marianaGarcez). Constants now flow through std::stoull instead of std::stod; lambda gets two nautilus::val args instead of one nautilus::val.

No generated C++ committed in this PR — the maintainer (cc @marianaGarcez) runs the generator on a chosen MEOS-function batch, reviews output, ships operators in follow-up PRs at a controlled pace. Why no generated code in this PR: - Generator author cannot build NebulaStream (full C++23 + vcpkg toolchain not available in author's environment); shipping unverified generated code would risk batched-broken operators. - Per-function review value: maintainer iterates on templates with the first batch's build feedback before scaling up. - Template iteration cost: first-pass templates may need adjustment after first build; smaller blast radius if only the generator lands. What lands: - tools/codegen/codegen_nebula.py — Python generator with embedded C++ templates derived 1:1 from the hand-written TemporalEDWithinGeometry operator shape (logical/physical/.hpp/.cpp) - tools/codegen/codegen_input.example.json — first-wave input list (5 spatial-relation E/A predicates: EDisjoint, ATouches, ECovers, ACrosses, EOverlaps over tgeo_geo) - tools/codegen/README.md — full design proposal: why codegen, what the generator produces, recommended scaling-wave sequence (W1-W5), what the generator does NOT do (CMakeLists / parser / grammar remain manual paste for idempotence), compile-verification note Smoke-verified: the generator runs locally + emits 5 operators × 4 files = 20 well-formed C++ source files; templates produce syntactically-reasonable output matching the existing operator style. Scaling path (recommended sequence): - W1: 5 spatial-relation E/A predicates (the example input) — first follow-up PR - W2: All ever/always spatial-relation predicates over tgeo_geo (~18 functions) — second follow-up PR - W3: Distance functions over tgeo_geo and tgeo_tgeo (~30) — third - W4: Scalar accessors that decompose to per-event reads — template extension required - W5: Aggregations (windowed/cross-stream) — separate generator with the aggregation-specific 4-layer pattern Stacks on PR #20.

SerializableAggregationFunction proto declares only {type, on_field, as_field}. The 5 MEOS aggregations landing in #16/#17 read additional fields out of the proto (vidA/vidB/dMeet/...), so they need the extra field. Adds: repeated SerializableFunction extra_fields = 4; Backwards-compatible (tag 4, new repeated). Aggregations whose extra fields are absent continue to deserialize unchanged. 2. CrossDistance/PairMeeting/TemporalLength aggregations carry an unused PipelineMemoryProvider& parameter on lower(). Werror=-Wunused-parameter turns that into a build failure. Annotates the parameter [[maybe_unused]] at the call site — no behavior change, intent stays visible to readers who later wire memory into the lowering.
