fork

Operator

  fork — copy values to parallel pipeline branches

Synopsis

fork (
  => <branch>
  => <branch>
  ...
)

Description

The fork operator copies each input value to multiple, parallel branches of the pipeline.

The output of a fork consists of multiple branches that must be merged. If the downstream operator expects a single input, then the output branches are merged with an automatically inserted combine operator.

Examples

Copy input to two pipeline branches and merge

echo '1 2' | zq -z 'fork (=>pass =>pass) | sort this' -
