arcadedb-embedded-native (PREVIEW)

Preview, alpha quality. This is an experiment, not a release. The API follows arcadedb-embedded, but the engine runs as a GraalVM native-image shared library, a different runtime with its own bugs. Do not use it for data you cannot lose. Versions are pre-releases (26.10.2.dev1): pip install --pre arcadedb-embedded-native. Report problems at https://github.com/humemai/arcadedb-embedded-python/issues and say that you use the native wheel.

ArcadeDB (SQL, openCypher, document, graph, vector, time series) embedded in your Python process without a JVM and without JPype. The engine is compiled ahead of time with GraalVM Community Edition to a shared library (libarcadedb.so, .dylib or .dll); Python loads it with ctypes.

Install

pip install --pre arcadedb-embedded-native        # or: uv add --prerelease allow arcadedb-embedded-native

It installs beside arcadedb-embedded (distinct distribution name, distinct import name arcadedb_native, no shared files). Extras for the columnar helpers: [numpy], [arrow], [pandas], [polars].

Use

The public API is the one of arcadedb_embedded. Switch with one line:

import arcadedb_native as arcadedb      # was: import arcadedb_embedded as arcadedb

with arcadedb.create_database("/tmp/demo") as db:
    db.schema.create_vertex_type("Person")   # schema objects work; see "Not supported yet" for the Java-object corners
    with db.transaction():
        db.command("sql", "CREATE VERTEX Person SET name = ?", "Ada")
    print(db.query("sql", "SELECT FROM Person").to_list())

arcadedb_native.ENGINE_VERSION, .NATIVE_IMAGE and .SOURCE_COMMIT tell which engine and which build you have.

Platforms

CPython 3.11 to 3.14; one wheel per platform serves every Python version because the library is loaded with ctypes, not compiled against CPython. Images are built for the baseline CPU of the platform (-march=compatibility).

Intel macOS and Windows arm64 are not built.

Not supported yet

Each of these raises NotOnNativeYet (a NotImplementedError) instead of misbehaving:

• JVM-only APIs: get_java_database(), start_jvm(), jvm_kwargs, JVM settings, jar_fingerprint(), direct Java class access.
• Java-object returns of schema methods (for example getClass, newLightEdge), VectorIndex.get_stats, and VectorIndex.find_nearest_approximate over PRODUCT quantization (PQ accessors).
• Async transaction() helpers that depend on Java threads.
• Engine modules left out of the image: gRPC, MongoDB wire, Raft/HA, Gremlin (the in-process server, the HTTP API, Postgres, Redis and Bolt wire protocols are in).
• Free-threaded Python builds are untested.

The parity suite (the bindings' own tests run against the installed wheel) passes with 0 failures; the remaining tests are the "not yet" items above or JVM-only by nature. Numbers are in the project notes, not here.
