Rename Fields
CAUTION
This transform has been deprecated in favor of the remap
transform, which enables you to use Vector Remap Language (VRL for short) to
create transform logic of any degree of complexity. The examples below show how you can use VRL to
replace this transform's functionality.
.new_name = del(.old_name)

Conflicts
State
This component is stateless, meaning its behavior is consistent across each input.
