⚡ Bolt: Optimize NetworkxBuilder._populate_nodes loop #41
Conversation
Hoists `_parent_node_id` calculation and `UniverseNode` check out of the node generation loop. This reduces redundant method calls and dict iterations for each generated node, resulting in ~15% speedup for nested graph generation. Also includes linting fixes for unused imports in `src/graphinate/builders/networkx.py`.

💡 What: Hoisted
_parent_node_idcalculation andUniverseNodecheck out of the inner loop inNetworkxBuilder._populate_nodes.🎯 Why: The
_parent_node_idmethod iterates overkwargsto reconstruct the parent ID tuple. Doing this for every single node in the generator loop is redundant (O(N*M) complexity where N is nodes and M is kwargs size) becausekwargsandnode_type_absolute_idare invariant during the loop iteration.📊 Impact: Benchmarks show a ~15% reduction in execution time (from ~1.65s to ~1.41s) for generating a nested graph with 100,000 nodes (200 parents * 500 children).
🔬 Measurement:
Tested with a benchmark script generating 100,000 nodes in a 2-level hierarchy.
Baseline: ~1.65s
Optimized: ~1.41s
Speedup: ~14.5%
Verified with existing test suite to ensure no regressions.
