Ask HN: Good tech talks on how analytics systems are implemented?

I am doing a new sub-system, for analytics, which I can design / implement from scratch. I get a bunch of unique users (say a few thousands). Now I need to track each of these users and do some analytics (Which places are they logging in from ? How long do their sessions last on average ? What are the usual links/endpoints that they visit ? etc.) in my API server. I have a few thousand active users and about two dozen parameters on which I want to track and analyze these parameters. I have never implemented such an analytics type system. I want to learn about people who have already implemented similar systems. Are there any good tech talks, engineering blog posts, video courses, etc. that highlight the design/technology/architecture choices and their benefits.
