# Aggregator

Fleets is Zerve's built-in feature for parallel processing. With a single line of code, users can parallelize code to run across multiple blocks. 

Aggregator block can be used to gather all the result from the parallel runs with gather function and convert to single variable. More information about Fleet is [here](/guide/canvas-view/fleets.md)
