FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package backoffv2
BackoffV2 
BackoffV2 is a PHP 5.5+ library implementing various backoff algorithms, such as exponential backoff.
This library only returns a backoff delay amount based on the selected algorithms; implementation of the actual delay mechanism (such as sleep()) is left to the user.
Installation
Install BackoffV2 with Composer:
composer require patinthehat/backoffv2
Implementation
"Jitter" is implemented, if you choose to use it. Jitter is a small, variable amount of time that is added to the backoff amount.
Available Jitter algorithms (roughly based on this post) include:
- NoJitter - No jitter
- FullJitter - Standard jitter amount
- EqualJitter - More consistent jitter amounts
- DecorrelatedJitter - Higher jitter amounts
Backoff algorithms include:
- ExponentialBackoff - exponentially increase the backoff amount
- ConstantBackoff - use the same backoff amount, regardless of the attempt count.
- LinearBackoff - linear increase of the backoff amount, i.e. 1, 2, 3, 4, ...
Usage
Using the Backoff class
BackoffV2 implements a main class, Backoff, that acts as a container and manager for the backoff and jitter algorithms you choose.
The constructor signature for Backoff is:
