Gallop

Enable to give some throttling to concurrent executions in bash (or other) scripts.

Build

Important

must be executed on a linux amd64 or arm64 depending on your target platform.

mvn clean install arthur:native-image

Idea

The idea behind the program is to create a thread pool (arbitrary set to the concurrency size but this is a detail) and associate to it a throttler (Semaphore). The concurrency set in the start command will limit the enabled concurrency for exec done by the exec command.

This enables to submit hundreds of tasks and throttle them without having to take care of that in the script which is always very fragile.

Tip	using multiple identifiers - we recommend to use ` identifier - the script pid - as base but you can decline it, ex `_pool1 - you can have multiple concurrency in the same script.

Usage
