Derived from Dgraph (github.com/dgraph-io/dgraph) at commit 64804bd2, Apache-2.0. See NOTICE. WHAT THIS IS. The graph engine as a Go library: posting lists, the DQL parser, the type and tokenizer system, the index and schema layers, and the wire types. 39,170 lines of the upstream's 166,337. THE STORE is github.com/luxfi/zapdb, a Badger fork that kept the package name, the subpackages (options, pb, y) and the API — Open, OpenManaged, DB, Options — so the 74 import sites are aliased rather than rewritten. THE CODEC is ZAP. zapdb serializes with ZAP, not protobuf: its pb package builds the ZAP types by default and the protobuf ones only under `-tags grpc`, a path that does not compile (table/builder.go calls pb.Marshal, which that tag removes). One call site in posting needed converting; every other type here is Hanzo's own protobuf and is untouched. NO TRANSPORT. An embedded engine dials nothing, so nothing here imports google.golang.org/grpc. Removed: 20 transport functions in x, the generated service stubs for Raft, Zero and Worker (1,657 lines), and the JWT helper — identity belongs to IAM. The core called none of them. NOT KEPT: worker, conn, raftwal, the cluster commands, the GraphQL layer and the test harnesses. `query`, the DQL execution engine, went with them because it depends on worker; parsing DQL is available here, executing it is not. The history of the upstream project lives at github.com/dgraph-io/dgraph. This repository begins at the derivation because three quarters of that history describes code this fork does not carry.
