    Epic Summary

    Summary

This project is about separating the source data for making Balancer decisions from the routing information so that scaling a cluster doesn’t require linearly growing the number of chunks. 

Motivation

Today, the more data a customer has, the higher the write unavailability from chunk migrations. We want to decouple the impact of chunk migrations from customer data size.
