# How We Monitor and Run Kafka at Scale
- **期号**: SRE Weekly Issue #23（2016-05-15）

## 简介
SignalFx shares their in-depth experience with Kafka in this article. This reminds me of moving around ElasticSearch indices:
> Although Kafka currently can do quota-based rate limiting for producing and consuming, that’s not a applicable to partition movement. Kafka doesn’t have a concept of rate limiting during partition movement. If we try to migrate many partitions, each with a lot of data, it can easily saturate our network. So trying to go as fast as possible can cause migrations to take a very long time and increase the risk of message loss.
