AsyncConfig

The AsyncConfig module enables admin config save asynchronously, which saves configuration in a queue, and processes it in a first-in-first-out basis.

AsyncConfig values:

• 0 — (Default value) Disable the AsyncConfig module and use the standard synchronous configuration save.
• 1 — Enable the AsyncConfig module for asynchronous config save.

To enable AsyncConfig, set the config/async variable in the env.php file. For example:

<?php
      'config' => [
               'async' => 1
       ]

Alternatively, you can set the variable using the command-line interface:

bin/magento setup:config:set --config-async 1
