collect — aggregate values into array
collect(any) -> [any]
The collect aggregate function organizes its input into an array. If the input values vary in type, the return type will be an array of union of the types encountered.
Simple sequence collected into an array:
echo '1 2 3 4' | zq -z 'collect(this)' -
=>
{collect:[1,2,3,4]}
Continuous collection over a simple sequence:
echo '1 2 3 4' | zq -z 'yield collect(this)' -
=>
[1]
[1,2]
[1,2,3]
[1,2,3,4]
Mixed types create a union type for the array elements:
echo '1 2 3 4 "foo"' | zq -z 'collect(this)' -
=>
{collect:[1,2,3,4,"foo"]}
