Functions

func ParallelizeUntil

func ParallelizeUntil(ctx context.Context, workers, pieces int, doWorkPiece DoWorkPieceFunc, opts ...Options)

ParallelizeUntil is a framework that allows for parallelizing N independent pieces of work until done or the context is canceled.

func WithChunkSize

func WithChunkSize(c int) func(*options)

WithChunkSize allows to set chunks of work items to the workers, rather than processing one by one. It is recommended to use this option if the number of pieces significantly higher than the number of workers and the work done for each item is small.
