ciudilo / telescoping_delete.js
Created January 16, 2017 15:19 — forked from achille/telescoping_delete.js
/*
* Auto-tuning delete that allows for removal of large amounts of data
* without impacting performance. Configurable to a target load amount.
*
* How it works:
* TL;DR: Delete a small slice every second; Vary the size of each slice
* based on how long the previous delete took; sleep; repeat.
*
* Intuition: If target is 100ms but delete took 50ms then
* we'd like to double the window size.
