adbdgl-adapter 1.0.2

Convert ArangoDB graphs to DGL & vice-versa.

ArangoDB-DGL Adapter

The ArangoDB-DGL Adapter exports Graphs from ArangoDB, a multi-model Graph Database, into Deep Graph Library (DGL), a python package for graph neural networks, and vice-versa.

About DGL

The Deep Graph Library (DGL) is an easy-to-use, high performance and scalable Python package for deep learning on graphs. DGL is framework agnostic, meaning if a deep graph model is a component of an end-to-end application, the rest of the logics can be implemented in any major frameworks, such as PyTorch, Apache MXNet or TensorFlow.

Quickstart

Get Started on Colab:

# Import the ArangoDB-DGL Adapter
from adbdgl_adapter.adapter import ADBDGL_Adapter

# Import a sample graph from DGL
from dgl.data import KarateClubDataset

# This is the connection information for your ArangoDB instance
# (Let's assume that the ArangoDB fraud-detection data dump is imported to this endpoint)
con = {
    "hostname": "localhost",
    "protocol": "http",
    "port": 8529,
    "username": "root",
    "password": "rootpassword",
    "dbName": "_system",
}

# This instantiates your ADBDGL Adapter with your connection credentials
adbdgl_adapter = ADBDGL_Adapter(con)

# ArangoDB to DGL via Graph
dgl_fraud_graph = adbdgl_adapter.arangodb_graph_to_dgl("fraud-detection")

# ArangoDB to DGL via Collections
dgl_fraud_graph_2 = adbdgl_adapter.arangodb_collections_to_dgl(
        "fraud-detection", 
        {"account", "Class", "customer"}, # Specify vertex collections
        {"accountHolder", "Relationship", "transaction"}, # Specify edge collections
)

# ArangoDB to DGL via Metagraph
metagraph = {
    "vertexCollections": {
        "account": {"Balance", "account_type", "customer_id", "rank"},
        "customer": {"Name", "rank"},
    },
    "edgeCollections": {
        "transaction": {"transaction_amt", "sender_bank_id", "receiver_bank_id"},
        "accountHolder": {},
    },
}
dgl_fraud_graph_3 = adbdgl_adapter.arangodb_to_dgl("fraud-detection", metagraph)

# DGL to ArangoDB
dgl_karate_graph = KarateClubDataset()[0]
adb_karate_graph = adbdgl_adapter.dgl_to_arangodb("Karate", karate_dgl_g)
