Concepts Overview - CefasDB Docs

Documentation excerpt

CefasDB is a high-performance NoSQL key-value and document database server. It accepts table, item, query, plugin, backup, and cluster operations over HTTP and gRPC; persists them in an embedded Pebble LSM tree; optionally replicates writes through raft; and exposes specialized query behavior through a plugin registry.

The simplest useful sentence is this: CefasDB stores typed document items in partition-keyed tables, adds SQL and PartiQL query surfaces, and lets plugins supply indexes, distance functions, estimators, and audience workflows without coupling those plugins to engine internals.

Architecture Overview shows the full request path: CLI or SDK, gRPC handler, catalog, storage, planner, plugin registry, raft, metrics, and tracing.

Data Model explains tables, partition keys, sort keys, attribute maps, conditions, TTL, backups, and streams.
