Rollup with leaky bucket

Experiment #7122nd March, 2021by Joshua Nussbaum

Continuing with the previous experiment using debounce to rollup multiple messages, the problem with debounce is that the window is static. I want an abstraction that supports a dynamic period.

For example, the window could start at 1s, but when there are a ton of messages or when we know it’s a high volume account, the window should increase proportionaly. So I need a different abstraction.

In this experiment, I change the code to use a “Leaky Bucket”. It’s basically a queue (array) that drains periodically.

I will look making the drain interval dynamic, based on the data rate.
