workerpool alternatives and similar packages
Based on the "Goroutines" category.
Alternatively, view workerpool alternatives based on common mentions on social networks and blogs.
-
semaphore
Semaphore pattern implementation with timeout of lock/unlock operations based on channel and context. -
neilotoole/errgroup
Drop-in alternative to sync/errgroup, limited to a pool of N worker goroutines. -
Hunch
Hunch provides functions like: All, First, Retry, Waterfall etc., that makes asynchronous flow control more intuitive. -
goccm
Go Concurrency Manager package limits the number of goroutines that allowed to run concurrently. -
conexec
A concurrent toolkit to help execute funcs concurrently in an efficient and safe way.It supports specifying the overall timeout to avoid blocking and uses goroutine pool to improve efficiency. -
go-tools/multithreading
Manage a pool of goroutines using this lightweight library with a simple API. -
queue
Gives you a sync.WaitGroup like queue group accessibility. Helps you to throttle and limit goroutines, wait for the end of the all goroutines and much more. -
hands
A process controller used to control the execution and return strategies of multiple goroutines. -
concurrency-limiter
Concurrency limiter with support for timeouts , dynamic priority and context cancellation of goroutines. -
oversight
Oversight is a complete implementation of the Erlang supervision trees.

Go simple async worker pool.
π ABOUT
Worker pool is a software design pattern for achieving concurrency of task execution. Maintains multiple workers waiting for tasks to be allocated for concurrent execution. By maintaining a pool of workers, the model increases performance and avoids latency in execution. The number of available workers might be tuned to the computing resources available.
You can read more about worker pools in Go here.
