📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal

The main goal of this session was to redesign the Flowpower Executor and implement a modular architecture for it, while also setting up an API server using FastAPI to enhance its execution capabilities.

Key Activities

  • Reimagining the Flowpower Executor: A comprehensive redesign was outlined, focusing on its responsibilities, suggested signatures, and modular dispatch logic to enhance robustness and production readiness.
  • Modular Executor Implementation: Developed a modular version of the executor.py file for the Flowpower architecture, incorporating batch, node, and streaming execution capabilities using PromptFlow.
  • Debugging PromptFlow: Diagnosed input mapping issues in PromptFlow, providing solutions and suggesting CLI improvements.
  • API Server Setup: Demonstrated how to set up an API server using FastAPI to run flows and trace their execution.
  • RESTful Endpoints: Implemented endpoints.py and chat_adapter.py for a RESTful and stream-capable application for Flowpower.

Achievements

  • Successfully redesigned and implemented a modular executor for Flowpower.
  • Set up a FastAPI server to manage flow execution and trace information.
  • Developed RESTful endpoints with streaming capabilities.

Pending Tasks

  • Further testing of the redesigned executor and API server.
  • Optimization of the CLI based on debugging insights.
