tigergraph__has_edge
Check if an edge exists between two vertices in a TigerGraph graph. Use to verify relationships efficiently before adding or querying edges.
Instructions
Check if an edge (relationship) exists between two vertices without retrieving its data.
Use When: • Verifying relationship existence • Validation logic • More efficient than get_edge when you only need existence check
Quick Start:
{
"source_vertex_type": "Person",
"source_vertex_id": "user1",
"edge_type": "FOLLOWS",
"target_vertex_type": "Person",
"target_vertex_id": "user2"
}Tips: • Returns boolean (true/false) • Faster than get_edge when you don't need the data • Use before add_edge to avoid duplicates
