Hey Maxwell, Sorry for the late response. Busy period and I am just catching up on everything on our MLs.
Can you summarize what you want to suggest and what questions you have for the ML, please? I quickly checked the ticket and I agree with Dmitry that a CEP would be needed. There is some mention about different approaches from other databases and I guess you want to discuss them before spending time on actual CEP? It seems how the grammar should look like was the main question? Happy to talk. Please share what you have in mind and we can give some feedback.
