# OriginChainDB

> OriginChainDB is a distributed multimodal database for connected applications and production AI. SQL, vector similarity, graph traversal, and full-text search share one managed engine. Natural-language `/ask` provides another way to query that data.

OriginChainDB is operated by Silicoyn Technologies Pvt Ltd. Applications connect structured records, embeddings and full-text indexes through shared identifiers, and declare graph relationships in their schemas. Row, vector and full-text ingestion use separate APIs; the application supplies embeddings and coordinates these writes. Dedicated instances offer single-tenant compute in a chosen region, with optional asynchronous standby replication. Replication and recovery limits are detailed below and in the deployment documentation.

## Key facts for retrieval

- **Data models:** SQL records, vectors, full-text indexes and graph relationships use one database engine. Ask is a query interface, not a fifth storage model.
- **Ingestion:** records, vectors and full-text documents use separate requests. Applications generate embeddings, coordinate writes and combine retrieval results. Shared IDs connect indexes back to source records.
- **Vector search:** available index types and search settings are documented in the vector reference. Compare recall and latency using the published workload and methodology; in-process results are not managed HTTP latency guarantees.
- **Write durability:** consult the operation and deployment documentation for acknowledgement, secondary-index persistence and recovery behavior. Do not infer a cross-model snapshot or a multi-request transaction from a successful row write.
- **Replication:** dedicated primary/standby configurations replicate asynchronously. Acknowledgement does not wait for the standby. Promotion is configuration-dependent; automatic promotion is opt-in and off by default. Consult the operations guide for lease, lag and recovery conditions. This is not synchronous quorum commit or a zero-data-loss guarantee.
- **Backups:** dedicated recovery options and current preview limitations are documented in the operations guide. Snapshot recovery, change archiving and restore-to-timestamp have different prerequisites. Free and pooled configurations do not include point-in-time recovery.
- **Deployment model:** managed cloud. Free uses shared, scale-to-zero infrastructure. Upcoming pooled configurations use shared compute capped at 1 vCPU, a single node in India (Mumbai), and no adjustable hot-data memory, high availability, replicas or additional nodes. Dedicated configurations run on virtual machines that serve only that one customer. In-place changes between free, pooled and dedicated are not available yet.
