Currently this plugin rejects a set proportion of events, at completely random. This results in properly reduced event load, which is great!

There's a risk of a decrease in data quality though: it's not good to lose random events of a single user, because we lose valuable data on what the user has done in the product, which may easily make insights invalid. It's better to instead reject users at random. The end result is the same number of events (statistically), but the quality of insights is still high, because every user's history stays complete.

Here's a pretty interesting article from Mixpanel on the topic of downsampling, which touches on this: https://mixpanel.com/blog/query-time-sampling/

We'll want to add this to the official plugin repository and publish in PostHog Cloud, but we can't have a logo with a Shutterstock watermark for that. May be good to request a design from Lottie.

Allow for specific events to be downsampled

ex: Certain events are less important than others and it would be nice to be able to downsample specific events
