Thanks for sharing this, truly inspiring. A few questions: (1) What do you like the most about langgraph, have you tried platforms like autogen? (2) Why using BullMQ with node, why not a solution like Temporal? (3) I didn't got you usecase regarding memory check pointer? if things can re-run at negligible cost why do we need it? (4) For sentimental analysis for chats are you using batch inferencing? Probably a loop keeping ready "interesting" chats for review (5) this 30 days analysis is it happening parallelly or is it a sequential loop? why not using something like Airflow for this?
