# Pivot Processor
|
|
|
|
|
|
|
|
|
|
You can use the `pivot` processor to rotate single valued metrics into a multi
|
|
|
|
|
field metric. This transformation often results in data that is more easily
|
|
|
|
|
to apply mathematical operators and comparisons between, and flatten into a
|
|
|
|
|
more compact representation for write operations with some output data
|
|
|
|
|
formats.
|
|
|
|
|
|
|
|
|
|
To perform the reverse operation use the [unpivot] processor.
