Market Validation v3

SJSON Market Research

Hypothesis-driven validation with falsification tests, triangulated demand signals, and transparent scoring. Every claim labeled Fact vs Hypothesis.

3 Hypotheses 34+ Evidence Cards 8 Contradictions 6/8 Audit Passed
§1 Testable Hypotheses

Every artifact is tagged as: supports / weakly supports / contradicts / irrelevant for each hypothesis.

H1: Pain Frequency

"ML teams hit serialization bottlenecks often enough that they file issues and switch tools."

18 Supporting 4 Weak 2 Contradicting
Falsification Test: If <5 GitHub issues show actual tool switches (not just complaints), this hypothesis fails.

Current Status: 8 issues show behavioral proof (migrations, benchmarks, PRs). Hypothesis supported.

H2: ML-Specific Fit

"Those bottlenecks are specifically about tensors/graphs (not generic JSON), so ML-native types matter."

12 Supporting 6 Weak 3 Contradicting
Falsification Test: If MessagePack/CBOR (generic binary formats) solve the problem equally well, ML-native types don't matter.

Current Status: BentoML #4791 requests msgpack but doesn't solve tensor metadata. PyG issues are graph-specific. Hypothesis supported.

H3: Adoption Friction

"A drop-in serializer with no schema registry & good DX is adoptable in <2 weeks."

5 Supporting 8 Weak 1 Contradicting
Falsification Test: If 3+ PoC attempts take >4 weeks or require schema changes, adoption friction is too high.

Current Status: Not yet tested. Need 3 PoCs to validate.
§2 Evidence Cards

Each card separates facts from claims, includes quantification, decision signals, and verification plans. Not just complaints — behavioral proof.

ML Platforms

BentoML #4131
Opened Jun 2023 · 15 comments · Open
High Confidence
Problem Statement

NumPy → Protobuf serialization is 1000x slower than alternatives, blocking production deployment.

Direct Quote
"For large payloads BentoML's Numpy Protobuf serialization/deserialization is ~1000x slower and the JSON serialization/deserialization is ~3000x slower compared to Pickle..."

Our Claim (Hypothesis)

SJSON would provide 100x+ improvement over current Protobuf approach.

Verification Plan:
• Dataset: 1M×128 float32 tensor (512MB)
• Baseline: BentoML Protobuf serializer
• Metrics: serialize time, deserialize time, payload size
• Success: ≥50x improvement in latency
Alternative Explanation: The bottleneck might be Python GIL, not protobuf encoding. Test: benchmark with and without GIL release.

Graph ML

PyG #6979
Opened Feb 2024 · 12 comments · Open
High Confidence
Problem Statement

No standard way to convert graphs between DGL and PyG frameworks.

Direct Quote
"Feature request: Bridging the gap between DGL and PyG - allow converting DGL graphs to PyG instances. This would make it easier for users who have existing graph structures in DGL to switch to PyG without having to recreate their graphs from scratch."
Our Claim (Hypothesis)

SJSON with Node/Edge/GraphShard types solves this completely. Universal format for both frameworks.

Verification Plan:
• Dataset: OGBN-Products (2.4M nodes, 61M edges)
• Test: Export from DGL → SJSON → Import to PyG
• Metrics: Roundtrip fidelity, load time, memory
• Success: Zero conversion code, <10s load time
§3 Triangulated Evidence

Never rely on a single signal. Each segment validated across 3 evidence types: Public Pain, Behavioral Proof, Economic Proof.

Segment: ML Platforms (BentoML, MLflow, W&B)

A. Public Pain
BentoML #4131: 1000x slower serialization
BentoML #4791: MessagePack feature request
MLflow benchmarks: EAV model pain documented
15+ related issues across repositories
B. Behavioral Proof
BentoML PR #4189: Added PyArrow Tensor support
MLtraq fork: Built faster alternative to MLflow
W&B custom encoders: Built internal binary format
Ray Serve migration: Some users switched platforms
C. Economic Proof
Inference latency budgets: 10ms P99 SLAs
Cloud costs: Serialization adds compute costs
Job postings: "ML infrastructure" roles focus on perf
Enterprise contracts: Latency SLAs in service agreements

Triangulation Status: All 3 evidence types present. Conclusion stable if any one removed.

§4 Contradictions & Negative Evidence

Where SJSON is NOT the right solution. Logging contradictions makes research credible.

Where SJSON Is Not a Fit

Analytics/BI Workloads

Arrow/Parquet optimized for columnar analytics. SJSON is row-oriented streaming format — wrong paradigm for aggregations.

When this wins: Large analytical queries, data warehousing, SQL-on-files.

Strict Schema Enforcement

If you need compile-time type safety and schema enforcement, Protobuf's code generation is a feature, not a bug.

When this wins: Cross-team APIs, formal contracts, backwards compatibility guarantees.

Existing gRPC Infrastructure

If entire stack uses gRPC + Protobuf, switching to SJSON means rewriting transport layer.

When this wins: Large organizations with established gRPC ecosystems.

Non-ML JSON Workloads

For regular JSON APIs (user data, configs), standard JSON or MessagePack is simpler. ML types are overhead.

When this wins: Web APIs, configuration files, non-ML backends.

Competitors & Substitutes

Competitor Why They Win Where They Fail SJSON Wedge
Apache Arrow Zero-copy IPC, columnar, huge ecosystem Complex setup, no streaming ML-native streaming, simpler API
Protobuf + gRPC Industry standard, type safety No ML types, schema overhead Schema-free, native tensors
MessagePack Simple, fast, good libraries No tensor support, just bytes Same speed + ML semantics
Pickle Python-native, supports everything Security nightmare, Python-only Safe, cross-language
§5 Scored & Ranked Targets

Transparent scoring rubric: Pain Intensity × Frequency × Budget / Friction. No more "cool problems" with low adoptability.

Rank Company Pain Frequency Budget Friction Score

2 TensorFlow Data 5 5 5 4 31.3
3 PyTorch Geometric 5 4 3 2 30.0
4 DGL (Amazon) 5 4 4 3 26.7
5 Confluent Kafka 4 4 5 4 20.0

Formula: Priority = (Pain × Frequency × Budget) / Friction
