A Knowledge Unit is RushDB's atomic measure of structured knowledge created during a write operation. KU accumulates from records created, properties stored, relationships formed, and embeddings generated. Standard reads and queries are always free.
A record with 10 properties costs ~10 KU per write (0.5 base + 1 per property).
Nested objects are decomposed into separate linked records. Each child contributes its own KU; each link costs 0.25 KU.
Standard queries never consume KU. Embeddings cost 5 KU per record; vector search, raw Cypher, and deep traversals cost 5 KU per call.
