I have ran Rally on a staging instance and wanted to compare the performance to our existing production cluster. From the documentation:

`First of all: Please (please, please) do NOT run Rally against your production cluster if you are just getting started with it. You have been warned.`

If this is regarding creating and deleting indexes with the same names as the track, it won't be an issue. Will Rally affect the performance/take down the production cluster? I saw minimal latency issues when running against our staging instance.

Yes, it's about the 2 issues that were mentioned:

- As part of a race Rally prepares cluster configuration which includes steps such as index and index template **removal** (typically prior to subsequent recreation but with content determined by a Rally track, not the content that _could_ have been present in the production cluster).
- Rally can generate enough traffic to affect performance of the target cluster.

The exact impact depends on a Rally track definition vs. what's currently being used in the target cluster, track parameters (e.g. number of clients) and load driver(s) specification when compared with target cluster resources.
