Executing them concurrently bounds latency to the slowest tool call. +**Impact**: Reduced latency bottleneck from sequential execution. +**Measurement**: In a baseline benchmark script (`benchmark_retrieval_baseline.py`), running 3 tools with a simulated 0.5s I/O latency took ~1.5 seconds. After the concurrent implementation, the same benchmark (`benchmark_retrieval_concurrent.py`) took ~0.5s, confirming a ~3x performance improvement for 3 tool calls. diff --git a/benchmark_retrieval.py b/benchmark_retrieval.py new file mode 100644 index 0000000..955e5c4 --- /dev/null +++ b/benchmark_retrieval.py @@ -0,0 +1,89 @@ +import asyncio +import time +import sys +from unittest.mock import AsyncMock, MagicMock + +class MockPackage(MagicMock): + __path__ = [] + + def __getattr__(self, name): + if name == "__spec__": + return None + return super().__getattr__(name) + +# Make sure ToolMessage can be mocked specifically to avoid string conversion errors +class MockToolMessage: + def __init__(self, content, tool_call_id): + self.content = content + self.tool_call_id = tool_call_id + +mock_messages = MockPackage() +mock_messages.ToolMessage = MockToolMessage +sys.modules['langchain_core.messages'] = mock_messages + +sys.modules['langgraph'] = MockPackage() +sys.modules['langgraph.graph'] = MockPackage() +sys.modules['langgraph.types'] = MockPackage() +sys.modules['langchain_core'] = MockPackage() +sys.modules['langchain_core.prompts'] = MockPackage() +sys.modules['langchain_core.language_models'] = MockPackage() +sys.modules['langchain_openai'] = MockPackage() +sys.modules['neo4j'] = MockPackage() +sys.modules['pinecone'] = MockPackage() +sys.modules['openai'] = MockPackage() +sys.modules['langchain_google_genai'] = MockPackage() +sys.modules['langchain_anthropic'] = MockPackage() +sys.modules['pydantic'] = MockPackage() +sys.modules['pydantic_settings'] = MockPackage() +sys.modules['fastapi'] = MockPackage() +sys.modules['langchain_community'] = MockPackage() +sys.modules['langchain_community.document_loaders'] = MockPackage() +sys.modules['numpy'] = MockPackage() +sys.modules['motor'] = MockPackage() +sys.modules['motor.motor_asyncio'] = MockPackage() +sys.modules['google'] = MockPackage() +sys.modules['google.genai'] = MockPackage() +sys.modules['google.genai.types'] = MockPackage() +sys.modules['dotenv'] = MockPackage() + +import src.pipelines.retrieval +from src.schemas.retrieval import RetrievalResult, SourceRecord + +class DummyPipeline(src.pipelines.retrieval.RetrievalPipeline): + def __init__(self): + self.model = MagicMock() + self.model_with_tools = MagicMock() + self.neo4j = MagicMock() + self.vector_store = MagicMock() + + async def _execute_tool(self, tool_name, tool_args, user_id, top_k): + print(f"Executing tool {tool_name}...") + await asyncio.sleep(0.5) + return [SourceRecord(domain="dummy", content="dummy", score=1.0, metadata={})] + +async def main(): + pipeline = DummyPipeline() + + ai_response = MagicMock() + ai_response.tool_calls = [ + {"name": "searchprofile", "args": {"topic": "work"}, "id": "1"}, + {"name": "searchtemporal", "args": {"query": "recent events"}, "id": "2"}, + {"name": "searchsummary", "args": {"query": "summary"}, "id": "3"} + ] + pipeline.model_with_tools.ainvoke = AsyncMock(return_value=ai_response) + + final_response = MagicMock() + final_response.content = "answer" + pipeline.model.ainvoke = AsyncMock(return_value=final_response) + + pipeline._search_summary = AsyncMock(return_value=[]) + + print("Testing baseline (Sequential Execution)...") + start_time = time.time() + result = await pipeline.run(query="hello", user_id="user1") + duration = time.time() -
