Guides for the current console and APIs.

New guides cover the current console, one-time migration, saved embedders and embedding runs, PostgreSQL compatibility, and the vector record API. Each guide states the deployment requirements and known limits.

The Elasticsearch reference now describes dedicated deployment availability and the supported API subset, including scroll, Point-in-Time, extended statistics and index templates. Unknown URL parameters can be ignored; check supported options before relying on them.

This date records the documentation update, not a new engine release or the first availability of every feature. The versioned archive below retains its original entries.

v1.3

"Scale out"

Multi-node configurations reach GA - write throughput that scales with node count behind one endpoint, transactions that span nodes and commit atomically, point-in-time recovery to the roll-up window, and rate budgets that grow with your configuration.

Release details5 notes
  • feat Multi-node configurations are generally available. Pick a node count when you build your configuration: write throughput scales with nodes (~2x measured at 2 nodes), data distributes across nodes automatically table by table, and your application keeps talking to a single endpoint with a single key - no client-side routing, no code changes. Each node can optionally carry its own synchronized standby through the same resilience configurations as single-node.
  • feat Atomic cross-node transactions. BEGIN / COMMIT / ROLLBACK over the SQL endpoint now spans tables on different nodes with the same all-or-nothing guarantee as a single node: every write in the transaction lands, or none do. ROLLBACK is idempotent and always safe to call; a lost transaction surfaces as a clean 409 with zero partial writes. See the new Transactions reference in the docs.
  • feat Point-in-time recovery: restore an instance to a roll-up boundary, with integrity verification on the restored data before it serves traffic. Driven from the console or the API. The archive window that bounds how close to a chosen moment you can land is a server-side setting, not a measured recovery point.
  • feat Rate budgets now scale with node count. Per-key budgets (requests/sec, bytes/sec, natural-language queries/sec, concurrent queries) multiply by the number of nodes in your configuration, and the full aggregate budget is delivered through the single endpoint. 429 responses now carry an X-OC-Limit-Hit header naming exactly which budget you exhausted.
  • docs New docs pages: Transactions (lifecycle, error handling, the retry pattern) and Multi-node configurations (what you get, choosing a node count, growing later). The rate-limits reference is rewritten around the four per-key budgets - and why batch endpoints (~18x measured throughput vs single-row calls) are the first lever to pull.

v1.2

"Scale ceiling"

Vectors scale past 10M per tenant, graphs learn embeddings, full-text reduces to canonical lemmas, and multi-writer cluster replication stays on the roadmap - active-passive remains the only replication mode any shipped engine serves.

Release details12 notes
  • feat IVF and IVF-PQ vector indexes land end-to-end. IVF partitions vectors by inverted-file cells for 10M+ scale per tenant; IVF-PQ adds residualised product quantization per cell (the Jegou 2011 path) for 64× memory savings at D=128 and 768× at D=1536 OpenAI ada-002 dims. The CI acceptance floor is recall@10 >= 0.75 at nprobe=4 on a small planted-cluster corpus. 1M IVF bulk-load in 80 s.
  • feat Binary quantization (32× memory savings) and PQ quantization (64× at the headline config) attach to HNSW or IVF as separate index kinds. Pick the recall/memory tradeoff per-collection without rewriting your client code.
  • feat GraphSAGE attribute-aware node embeddings ship with three aggregator choices: Mean (fastest), MaxPool (best representational capacity per parameter), and LSTM (sequence-aware, deterministic per-(node, layer) shuffle so retrains converge to the same vector). Pairs with Node2Vec persistence for downstream similarity search.
  • feat Full-text lemmatization in 9 languages — English, Spanish, French, German, Italian, Portuguese, Russian, Dutch, Swedish — reduces inflected forms to a dictionary-backed canonical lemma. Higher precision than Snowball stemming on natural-language fields. Stemming for 18 languages remains available as a separate analyzer step. ICU + geo tokenizer ship alongside for mixed-script and location-aware queries.
  • feat Cypher v3 closes: CALL subqueries, nested FOREACH, list comprehensions (row-time), MERGE, DELETE, CREATE relation, and multi-hop undirected matches. The DELETE / CREATE path lands first; MERGE follows the same idempotent contract you'd expect from a Cypher implementation.
  • feat Materialized views with on-demand refresh: install_materialized_view computes the initial materialization, refresh_materialized_view re-runs the definition with an atomic overwrite. POST install / POST :name/refresh / GET :name. Incremental refresh stays on the roadmap.
  • feat Foreign keys and CHECK constraints (Phase B). FK on-delete supports NoAction, Restrict, and SetNull at write-time; Cascade and SetDefault are deferred. CHECK expression language: literals, =/!=/</<=/>/>=, AND/OR/NOT, IS [NOT] NULL, IN — with 3-valued logic.
  • feat JOIN cap raised from 5 to 32 tables. Left-deep planner; analytics rollups across a long dimension chain no longer hit the ceiling.
  • feat Multi-writer (quorum) cluster replication is roadmap, not a shipped mode, and has no scheduled date. No shipped engine commits a write through consensus: a request to run a database in quorum mode is refused at config-install time rather than accepted and quietly degraded, and the consensus machinery runs only on engines explicitly configured for engineering drills. Active-passive replication is the supported mode and the default for every tenant.
  • feat Serializable MVCC Phase B (preview): per-key version chains with !ts prefix-scan-from-newest give O(1) conflict detection at ~28-byte overhead per version. Range-serializability via gap locks is Phase C work.
  • feat PostgreSQL ingest connector v1 (POST /v1/.../ingest/postgres/sync) pulls rows from an existing Postgres source into your OriginChainDB tenant — no separate ETL service needed.
  • feat Python SDK adds typed namespaces: oc.sql, oc.vector, oc.fts, oc.graph. IDE autocomplete works against the shape you're actually using.

v1.1

"Hardening"

Transactional email, crash-injection in CI, shape-level diagnostics, and a fistful of dashboard fixes.

Release details16 notes
  • feat Forgot- and reset-password flow shipped end-to-end. Request a reset link from /forgot, set a new password from /reset-password - single-use, time-limited tokens delivered through our managed transactional email service.
  • feat Magic-link login and password-reset emails now go through our managed transactional email service. Delivery is signed, DKIM-authenticated, and falls back to a journal log if the provider has a hiccup so you never lose access.
  • feat Crash-injection harness lives in CI. Every commit crashes the engine at four critical durability boundaries twenty times each - recovered state must be a prefix of a known-good model. 4×20 = 80 green on every push.
  • feat Optimiser landed on the hot path: cost-based shape routing now picks the cheapest plan from a small fixed menu instead of always taking the first match. No tuning knobs to learn.
  • feat Synchronous-replica catch-up now uses an explicit sync state-machine - followers report replication delay in real time and the primary refuses to ack writes until the standby is caught up.
  • feat Configuration-upgrade flow in the dashboard: change compute configuration from Single-zone → HA → HA+ without recreating the instance. Rolling resize, no downtime, prorated on the next bill.
  • fix Billing math: monthly spend now includes only running instances. Stopped instances no longer accrue compute charges in the current-cycle estimate (storage still does, since data still lives on disk).
  • fix Admin login: the auth-gate IIFE no longer fires on / or /magic-link, so the reload loop reported on a few accounts is structurally impossible. Login form is always interactive, even before boot-status comes back.
  • fix Dashboard /app/backups: hoisted the tenant-ownership check out of an N+1 loop and translated AbortError into a friendly retry banner. List-backups no longer SIGNAL_ABORTED on instances with hundreds of backups.
  • fix Console snapshot list now caches results for 30 s and the SDK times out at 60 s - slow snapshot directories no longer hang the page.
  • fix Public docs: scrubbed a leaked tenant ULID and replaced with the acme.* placeholder used elsewhere.
  • fix Crash-replay test corpus expanded - every persisted shape now has a deterministic replay test.
  • perf Per-repo CI: each crate, each SDK, and the frontend run in their own pipeline. Builds that don't touch a target skip its tests entirely - typical PR feedback dropped from ~9 min to ~2 min.
  • docs New blog post: "Crash at every durability boundary" - how the new crash-injection harness works and why it caught two real bugs the day it landed.
  • docs New blog post: "One commit, every shape" - how multi-shape writes commit atomically as a single durable unit.
  • docs New blog post: a deep-dive on how the cost-based optimiser picks shape routes.

v1.0.1

"Outreach"

Marketing surface, MCP server, and an OpenAPI 3.1 spec - built so AI agents and humans can both read OriginChainDB.

Release details11 notes
  • feat @originchain/mcp-server published - a Model Context Protocol server that exposes /rows, /query, /ask, /watch, and the add-on shapes to any MCP-aware client (Claude Desktop, Cursor, etc.). Drop in your bearer, point at your endpoint, you're live.
  • feat OpenAPI 3.1 spec published at /openapi.json - every public HTTP endpoint, every schema, every error code. Generate clients in any language, or paste it straight into your editor's HTTP plugin.
  • feat Eight head-to-head comparison pages: OriginChainDB vs Postgres, MongoDB, Neon, Supabase, Pinecone, Qdrant, Weaviate, and Milvus. Honest about where each tool wins and where ours does.
  • feat Site-wide search via Pagefind. Hit the search input on any page, get instant results across docs, blogs, and marketing pages - fully static, no backend, works offline once cached.
  • feat Real /status page wired to the same metrics the on-call dashboard reads. Per-region uptime, 30-day incident history, current SLO burn.
  • feat Schema delete in the dashboard: drop a key shape from the console with a typed-confirmation guard. Backed by new DELETE endpoints (DELETE /v1/schemas/:name with cascade flag).
  • feat Per-page Open Graph images: every marketing page renders a tailored OG card with its own title and category, so links look right on Slack, Twitter, LinkedIn, and Discord.
  • feat Mobile hamburger navigation across the marketing site, with dark theme as the default. Light theme toggle still available.
  • feat IndexNow ping on every deploy - search engines hear about new docs and blog posts within seconds of merge.
  • feat Three new long-form engineering blog posts on storage internals, replication, and the new add-on architecture.
  • fix Go SDK: corrected the module path to github.com/originchain-ai/originchain-go. `go get` and `go mod tidy` now resolve correctly.

v1.0

"Add-ons"

Six new paid add-ons attach to any configuration - opt in only what your workload needs. A seventh, the multi-writer cluster, was announced here but has not shipped. The prices below are the ones announced that day and are no longer the offer: SQL Pro was folded into every paid configuration on 2026-06-03, and Vector Search, Full-Text Pro and Graph followed on 2026-09-02 - all four are now included at no extra charge. MVCC Transactions and Intra-Segment PITR are still priced add-ons. A configuration is priced as a whole today - see pricing for what applies now.

Release details7 notes
  • feat SQL Pro add-on ($49/mo): GROUP BY with COUNT/SUM/AVG/MIN/MAX, INNER + LEFT/RIGHT/FULL OUTER joins, HAVING filters, and chained 3+ table joins (left-deep, up to five tables).
  • feat Vector Search add-on ($79/mo + $0.0002 per topk): HNSW with cosine, dot, L2 metrics and tunable speed/recall. Default high_recall mode hits recall@10 = 0.96 at 100k vectors with p99 109 ms; fast mode runs p99 37 ms at recall 0.69. Filtered topk via metadata equality, f32 SIMD distance kernels, deserialized graph cache.
  • feat Full-Text Pro add-on ($49/mo): Lucene-default BM25 (k1=1.2, b=0.75), phrase queries via position-list intersection, UAX #29 Unicode tokenizer, and Snowball stemming for 18 languages.
  • feat Graph add-on ($59/mo): forward and reverse one-hop neighbors (correct on self-relations), BFS up to a configurable max depth, path reachability, and weighted shortest path (Dijkstra) with caller-supplied weight functions.
  • feat Transactions add-on ($99/mo): multi-row snapshot-isolation transactions with optimistic conflict detection - begin / get / put / delete / commit / abort across multiple rows.
  • feat Intra-Segment PITR add-on ($149/mo): tighter point-in-time recovery via a continuous change stream with embedded microsecond timestamps. Preview - the archive window that bounds restore granularity is a server-side setting, not a measured recovery point.
  • feat Multi-Writer Cluster add-on (Enterprise): announced here as a multi-node write cluster with TLS transport and durable persistence. It has not shipped. Quorum replication remains roadmap with no scheduled date, a request to run a database in that mode is refused at config-install time, and every database in service runs the active-passive path.

v1.0

"Live deploy"

OriginChainDB reaches general availability - single-tenant, region-isolated, sub-100 ms in-region p99.

Release details5 notes
  • feat Single-tenant region-isolated compute live in Asia Pacific (Mumbai). Each instance gets a dedicated instance, durable transaction logging, and an HTTPS endpoint provisioned in about two minutes.
  • feat Standby replication on every paid configuration. A write is acknowledged once it is flushed to durable storage on the primary; frames stream to the standby continuously, asynchronously.
  • feat Three compute configurations (Single-zone, HA, HA+) and four storage configurations (20 GB to 2 TB). Resize compute and storage independently, hot, with no downtime.
  • feat Console-driven bearer rotation with a 60-second grace window for rolling deploys.
  • perf p99 read latency under 8 ms in-region on HA and HA+; cached /ask responses return in under 50 ms.

v0.12

"Failover"

Promoted-follower failover verified end-to-end on live infrastructure.

Release details4 notes
  • feat Snapshot-bootstrap: a new follower can join a running primary without operator intervention, receiving a consistent snapshot before tailing live frames.
  • feat Failover preserves full state - promoted follower serves reads and writes immediately on takeover.
  • perf Promotion is operator-triggered by default. An opt-in automatic promotion path also exists: it is off by default, a standby takes the writer role only once the writer lease has expired, an external restart hook completes the switch, and a standby that is not fully caught up refuses to promote.
  • perf Active-passive replication remains the production path. Promotion is fenced by a single-primary claim; because replication is asynchronous, an abrupt primary loss can still cost the most recent acknowledged writes.

v0.11

"Initial GA"

Engine, managed console, and Razorpay billing go live.

Release details4 notes
  • feat Managed console: signup, region selection, configuration selection, instance provisioning, metrics and audit log access.
  • feat Razorpay billing integration: USD pricing, monthly and annual cycles, prorated mid-cycle changes, hosted card capture at instance create.
  • feat Encrypted nightly backups with daily integrity checks; continuous-archive point-in-time recovery on every paid configuration.
  • feat Python SDK - fully typed, sync and async, with helpers for /rows, /query, /ask, /watch, /sql, /vector, /fts, /graph.
Link to this release

v0.10

"Compile"

Natural-language compile path runs fully in-region with no API key in the customer's path.

Release details4 notes
  • feat Every /ask call compiles in the same region as the tenant's instance. Credentials are scoped per instance and handled for you - no LLM API keys anywhere in the customer's stack.
  • feat Schema prompt caching: repeated /ask calls with the same catalog pay the cached-read rate (~90% discount on repeated catalog tokens).
  • feat Per-instance scope locked to a single model identifier - no other foundation models, no cross-tenant access.
  • perf Shared runtime + per-region inference client cache; SDK startup cost is paid once per process, not per /ask.
Link to this release

v0.8

"Production"

Hot-path concurrency, atomic backups, chaos and load harnesses.

Release details5 notes
  • feat MVCC-lite on hot-path writes - conflicting updates serialize per row without blocking reads.
  • feat oc backup create / oc backup restore - atomic at the filesystem level, with daily integrity checks.
  • feat Chaos and load harnesses run on every build (process kill, disk full, interrupted-write recovery; 10k rps steady-state).
  • feat HTTP body limit enforced at 8 MiB; rate limiter is a real token bucket with Retry-After headers.
  • perf Concurrent-read path reworked to remove a hot-index bottleneck - p50 reads down ~18%.
Link to this release

v0.7

"Reactive"

Live views over Server-Sent Events; durable plan cache.

Release details3 notes
  • feat New /v1/watch endpoint - Server-Sent Events stream of updates for a live expression. Same protocol across every region and configuration.
  • feat Plan cache spills to disk; cold start reloads hot plans without re-invoking the LLM.
  • perf Catalog lookup is lock-free; consult cost dropped to ~12 µs.
Link to this release

v0.6

"Consolidation"

Single managed engine replaces the multi-engine split.

Release details3 notes
  • breaking Storage consolidated onto a single managed engine - one recovery path, one backup path, one mental model. Earlier multi-engine split removed.
  • breaking Parquet, Arrow, DataFusion, and KuzuDB dependencies dropped.
  • feat Plans compile down to index, ref-walk, and range-scan primitives on the unified store. Cost-based routing retired - no routing to do.
Link to this release

v0.5

"First release"

Initial public release.

Release details2 notes
  • feat HTTP ingress, row-keyed store, and the natural-language to query-plan compiler land for the first time.
  • docs Specification document published; HTTP API documented.
