combine

Operator

  combine — combine parallel pipeline branches into a single output

Synopsis

( => ... => ...) | ...

Description

The implied combine operator merges inputs from multiple upstream branches of the pipeline into a single output. The order of values in the combined output is undefined.

You need not explicit reference the operator with any text. Instead, the mere existence of a merge point in the flow graph implies its existence and its semantics of undefined merge order.

Examples

Copy input to two pipeline branches and combine with the implied operator

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

=>
