tketool.storage

Extensible graphs, trees, maps, lists, and linked lists over replaceable ordered storage backends.

pip install tketool.storage

from tketool.storage import Graph, MemoryBackend, PersistentMap, Tree

backend = MemoryBackend()
settings = PersistentMap(backend, "settings")
settings.put("language", "zh-CN")

graph = Graph(backend, "knowledge")
person = graph.add_node("alice", {"name": "Alice"}, type="person")

Optional adapters:

pip install "tketool.storage[sql]"
pip install "tketool.storage[postgresql]"
pip install "tketool.storage[redis]"

The dependency-free adapters are MemoryBackend and SQLiteBackend. SQLAlchemyBackend uses SQLAlchemy Core and database-specific drivers; RedisBackend uses redis-py and an atomic Lua batch.

The old tketool.ml/tketool.ml2 and domain-specific StorageBase APIs are not retained. New backends only implement point read, ordered scan, atomic batch, and transaction primitives; new data structures compose those primitives without changing adapters.
