Supported commands for parallel reduce search processing
Parallel reduce search processing supports a growing list of commands. The following table describes commands that are currently supported. It also describes restrictions for using some commands that don't support parallel reduce in certain use cases because the nature of the commands do not allow them to be pushed to intermediate reducers.
In most cases, you don't need to know when searches run with parallel reduce search processing because Splunk software automatically takes advantage of this optimization as conditions allow. If parallel reduce search processing is restricted or not supported on a command, your searches continue to deliver results as expected without using parallel reduce search processing.
