Batch Insert

Efficiently load multiple edges at once using put_batch.

Use put_batch() to efficiently insert multiple edges in a single operation.

Inserting Multiple Edges

from cog.torque import Graph

g = Graph("movies")
g.put_batch([
    ("inception", "directed_by", "nolan"),
    ("inception", "genre", "scifi"),
    ("interstellar", "directed_by", "nolan"),
    ("interstellar", "genre", "scifi"),
    ("dunkirk", "directed_by", "nolan"),
    ("dunkirk", "genre", "war"),
])

Querying the Data

Find all films directed by Nolan by following incoming directed_by edges:

# All Nolan films
g.v("nolan").inc("directed_by").all()
# {'result': [{'id': 'inception'}, {'id': 'interstellar'}, {'id': 'dunkirk'}]}

Performance Tips

Use put_batch() instead of multiple put() calls for better performance
Set flush_interval when creating the graph for large imports:

g = Graph("movies", flush_interval=100)

Call g.sync() after batch operations to ensure data is persisted
