Consistency budgets and session tokens
Opaque, project-bound consistency tokens for read-your-writes, per-read freshness budgets, and replicas that forward tenant traffic to the primary through a bounded, streaming proxy.

Overview
An open-source (Apache-2.0) Rust database unifying documents, BM25 search, vectors, and realtime in one engine. Benchmarks are published with committed evidence files — including the adversarial cases where recall degrades. Its Database 2050 roadmap tracks 100 capabilities, each with a pass/fail evidence gate.

Database 2050 roadmap
100 capabilities, each with an explicit evidence gate. A capability counts as implemented only when its gate passes on the main branch. The work below is built and passing internal gates on review branches — it is not merged or released yet.
Transaction history checker
Searches recorded histories for G0, G1, G-single and G2 anomaly cycles with a bounded search — and reports “unverifiable” rather than a false pass when the bound is reached.
Restore-proven backups
A backup only counts once a restore to a fresh target verifies its manifest and watermarks. Adds incremental schedules, point-in-time restore, cross-region object copies, automated restore drills, and a retention-locked vault.
Crypto-agile encryption and key rotation
Envelopes record algorithm and key version, the write-ahead log derives a fresh key per record, and rotation drills enumerate every secret class — reporting any class that cannot rotate yet instead of skipping it.
Adaptive query governor
Live resource budgets bound scans, fan-out, and result sizes for every request.
Provenance for AI retrieval
Retrieval returns receipts naming source commits and ranking stages, vector indexes expose embedding freshness, and recall is fenced to a single index generation so a reindex can never mix results.
Versioned formats and data contracts
Explicit, compatible format envelopes for exports, plus executable data contracts that enforce compatibility, ownership, and privacy rules at boundaries.
Migration planning and two-way sync
A migration risk planner that inventories source shape, unsupported semantics, and rollback steps, and a bidirectional sync contract with explicit conflict semantics.
Governance by default
Continuous sensitive-data classification, portable compliance evidence packs with credential redaction, attribute- and purpose-based authorization, policy as code, field-level lineage, and workload identity with mTLS.
Data movement
Online schema evolution, a zero-downtime migration pipeline (snapshot, tail, verify, shadow-read, cutover), parallel bulk load and exit with checksums, and a federated query gateway.
Counts from the capability catalog on main (crates/server/resources/database-2050-capabilities.json) as of 26 September 2026. Nothing listed below is counted as implemented until it merges with its gate passing.
