sort

Type of operation: Metadata

Description

Sort rows in the dataset based on ordering functions applied to column fields or column name provided as arguments. If a column name is provided without an ordering function, the asc ordering is implicit. OPAL sort is not stable with respect to fields that are not being sorted.

Usage

sort ordering ...

Argument	Type	Required	Multiple	Constant
ordering	ordering	Required	Can be multiple	Variable

Accelerable

sort is always accelerable if the input is accelerable. A dataset that only uses accelerable verbs can be accelerated, making queries on the dataset respond faster.

Examples

sort foo

Sort the dataset by the column namned foo (default is in ascending order)

sort asc(podName), desc(clusterId)

Sort the dataset ascending by podName and descending by clusterId
