hive-yggdrasil-storage

Yggdrasil-backed versioned storage for the hive ecosystem — snapshot / branch / merge across heterogeneous backends under a shared Hybrid Logical Clock.

Domain-agnostic and hive-mcp-free: it depends only on yggdrasil, the storage drivers, and hive-dsl. Extracted from hive-mcp so the core no longer carries the yggdrasil / datahike / datalevin coupling.

Namespaces

ns	role
hive-yggdrasil-storage.adapters.datahike	yggdrasil.protocols adapter wrapping a Datahike conn (first-class versioning)
hive-yggdrasil-storage.adapters.datalevin	yggdrasil.protocols adapter wrapping a Datalevin store (snapshot as labelled tag)
hive-yggdrasil-storage.adapters.proximum	yggdrasil.protocols adapter wrapping a Proximum vector store
hive-yggdrasil-storage.workspace	late-bound facade over yggdrasil.workspace (degrades to nil + WARN if yggdrasil absent)
hive-yggdrasil-storage.pilot	coordinated-commit + per-branch fan-out orchestration over the adapters

Usage

(require '[hive-yggdrasil-storage.pilot :as pilot])

(pilot/register-adapters!
 {:memory {:kind :datahike  :handle conn  :system-name "hk-mem"}
  :carto  {:kind :datalevin :handle store :system-name "dl-carto"}})

(pilot/commit-on-wrap! {:session-id "smoke"})

The host owns the event bus and decides when to call commit-on-wrap! / branch-all-for-ling! / merge-all-for-ling! from its own lifecycle events.
