Benchmarked against PostgreSQL, VoltDB, and SingleStore — see Benchmark Matrix . - ✅ Low latency — single-shard fast-path commits bypass 2PC entirely; Hot Row Optimization keeps version chain depth-1 under high-contention update workloads - ✅ Provable consistency — MVCC/OCC under Snapshot Isolation, Wound-Wait deadlock prevention, CI-verified ACID - ✅ Vectorized execution — Filter + Project + Aggregate full vectorized path on RecordBatch ; fused streaming aggregates for large scans - ✅ Operability — 50+ SHOW commands, Prometheus metrics, AIOps engine, failover CI gate - ✅ Determinism — hardened state machine, bounded in-doubt, idempotent retry, WAL Pipeline Commit - ❌ Not HTAP — no analytical workloads - ❌ Not full PG — see unsupported list below FalconDB provides OLTP with fast/slow-path transactions, WAL-based primary–replica replication (gRPC streaming), promote/failover, MVCC garbage collection, vectorized query execution, and reproducible benchmarks. Deterministic Commit Guarantee (DCG) If FalconDB returns \"committed\", that transaction will survive any single-node crash, any failover, and any recovery — with zero exceptions. This is FalconDB's core engineering property, called the Deterministic Commit Guarantee (DCG) .
