I'm confused, why is this running a linear regression? Shouldn't it just be a windowed average over the last N runs?

This runs a pipeline with 1 element, then 300, then 600, and so on until 3000. We use the linear regression to measure per-element overhead, and base overhead of the runner, and report it.

Still feels very weird to me to be using a regression. Usually those are meant to build models/feature extraction, but this seems the benchmark only needs to report some windowed average. Anyway, that's a conversation for another time.

3) When the timer fires, change the key and output all the elements downstream

This executes the same codepaths that are run on the Fn API (and Dataflow)
workers, but is generally easier to run (locally) and more stable..

1) Put all the PCollection elements in state
2) Set a timer for the future
3) When the timer fires, change the key and output all the elements downstream

This comment is somewhat misleading. Technically, windows are state & timers but I don't know if many people will make that connection reading this code. Can you please rewrite what this microbenchmark does in terms of windowing?

Thanks. Great catch. I've rephrased this. LMK if htat looks better.
