Kotobase na graph database wey dey use content take identify data for AI state and knowledge. E keep relationships, where data come from, and history wey you fit identify together. Access dey limited to each tenant, and hosting dey managed.

Single-client production HTTPS latency, including network and authorization. Small two-pattern Datalog point selection; no be throughput, big-graph, controlled cold-cache, or competitor ranking claim.
Every measured query return di inserted marker. All 300 measured requests succeed.
Method plus raw resultsAgents dey forget between sessions. Retrieval dey return disconnected chunks. Operating graph infrastructure dey steal time from di app wey you dey build.
Make sure say useful entities, claims, and relationships dey available anytime you need am.
Show how people, events, documents, and decisions relate — no be only which text dey look similar.
Use hosted secure storage, then managed SLA when production team need am.
Give agents memory wey go survive di session instead of isolating knowledge for chat history.
You fit store and find entities, claims, plus relationships, no be only disconnected pieces.
Make the same tenant-scoped graph show through APIs and MCP.
Keep graph state and provenance safe with content-addressed commits.
Traditional RAG na good for finding related passages. Graph-backed AI add explicit entities, claims, and relationships so agent fit follow connected context.
Kotobase dey complement retrieval; e no talk say every workload suppose replace vector search.
Applications and agents fit access the graph inside the same tenant identity boundary.
Signed immutable commit CIDs dey make the selected graph state explicit and reproducible.
Clients fit query, cache, compute, and contribute verified CID-addressed results.
Give agents graph tool surface without to build one-off retrieval glue for every application.

Tools dey generated from the same published lexicons wey the application API dey use.
Represent di people, products, organizations, documents, and events wey your application dey reason about.
Keep assertions and their graph context dey available across sessions and applications.
Use Datalog, SPARQL, or Cypher-style query surfaces for di shape of query wey you need.
Bind work to content-addressed graph commits instead of implicit mutable database state.
Kotobase na option to check when you want knowledge graph for agents and applications, MCP access, managed hosting, or content-addressed provenance.

Production scope as of 2026-08-15. Supported syntax, measured evidence, and open gaps dem separate so result wey be only small part no go show as general graph-database performance.
| Area | Current production specification |
|---|---|
| Storage and truth | Signed immutable CID commit DAG; R2-backed immutable blocks and conditional graph heads. Durable Objects, D1, PostgreSQL, and an S3 mutable database no be correctness dependencies. |
| Di part of Cypher-style wey fit read | Labels, parameters, property projection, DISTINCT, ORDER BY/SKIP/LIMIT, NOT/AND/OR predicates, one materializing WITH stage followed by MATCH, simple CASE plus CASE WHEN variable IS NULL, and directed/undirected variable-length paths for primary and OPTIONAL MATCH. OPTIONAL traversal dey run under left join and e dey fill null for misses. For 2026-08-15 production probe, dem combine these new operators and e return the expected row through kotobase.net for graph Worker 838a5a03-f307-46f2-99b8-4717a0573096. This one still na small part, no be full openCypher or performance claim. |
| Planner and joins | Path-free basic graph patterns dem hand over to peer statistics planner as one BGP: e dey measure visibility-scoped clause cardinalities or e dey use fresh scoped materialized statistics, e dey cost-order clauses, then e dey pass estimates to join strategy. Hash natural joins and binding push-down dey used around OPTIONAL/WITH stages. Variable-length path interleaving still dey use bounded heuristics; no be general cost model for every Cypher operator. |
| Cypher writes | Authenticated CREATE of standalone nodes wey need non-empty id dey use the same graph-policy check, immutable transaction/commit blocks, conditional R2 head CAS, nonce replay protection, and conflict retry path like datom transact. For 2026-08-15 production probe, e create created/1 with HTTP 200 and read the graph back. Relationship CREATE, CREATE after MATCH, MERGE, SET, REMOVE, and DELETE dem no allow. |
| Di part of SQL JOIN wey fit read | Bounded SELECT over datoms and request-scoped external tables. INNER/LEFT/RIGHT/FULL/CROSS and non-equality joins, derived tables to depth 2, GROUP BY, and COUNT/SUM/AVG/MIN/MAX dey supported for up to four sources. Datom scans/results stop at 1,000 and intermediate joins at 10,000. External tables na finite scalar rows wey dem supply for the request, no be arbitrary network/database connectors. For 2026-08-14 production probe, e pass FULL external JOIN, grouped derived-table, and LEFT non-equality JOIN shapes; na functional evidence, no be performance claim. HAVING, CTE/UNION, windows, DML, comments, and multi-statements still no support. |
| Cold reads | CID verification, Cache API/R2 block fetch, query-ordered pack Range support, and bounded client caches. The published 12.5M-datom qualification policy need three independent empty-client-cache samples and cold network ceilings of 5 s for point lookup and 12 s for two-hop traversal; e receipt measure cold p99 2.231 s and 6.264 s. This one na reproducible engineering envelope for those two shapes, no be contractual SLA or arbitrary-query guarantee. |
| Same-graph writes | Optimistic conditional-head CAS, full-jitter exponential backoff, 12 attempts by default (operator-bounded 1–16), then HTTP 409 with Retry-After and retry metadata. Writes no be lock-free successes under arbitrary contention; no acknowledged write fit report before e CAS win. |
| Scale evidence | Historical LDBC SF-0.1 receipt: 3,013,602 datoms and five of seven Interactive Short queries. IS2's WITH shape and IS7's OPTIONAL path/CASE IS NULL shape now pass end-to-end tests, but the historical latency receipt never relabel or rerun. SF-1 convert to 25,522,216 datoms; no completed 100M-datom production qualification dey. |
| Comparison claim | No general Neo4j, Neptune, GraphDB, or Datomic performance superiority claim. No audited LDBC Neo4j result dey to compare; published local paired results na only for their exact bounded workloads. |
