> Performance is a common issue with CopyTable is when the key/time range for
> the data to be copied is large because it basically scans all rows on the
> specified range, in the source and perform related puts on the source. We
> should add extra note explaining that on the reference guide, to help
> users/admins understand when to choose between the different tools/approaches
> for syncing clusters.
