README

A robust Magento 2 module that provides a persistent, isolated cache layer untouched by Magento's default CLI cache operations (cache:clean, cache:flush).

Requirements

• Magento 2.4.8
• PHP 8.4

Module version

• 1.0.0

Why This Module?

In Magento 2, we often store temporary but critical data in cache — such as serialized payloads, or flags for ongoing processes. However, a major concern arises:

• Running Magento CLI commands like bin/magento cache:flush or cache:clean can wipe out these important entries, potentially breaking business logic or corrupting workflows.

Solution: Persistent, Isolated Cache

This module creates and manages a completely isolated cache frontend using its own identifier (parsistent). Magento CLI commands do not affect it — ensuring your critical data remains safe.

Features

• Immune to cache:clean and cache:flush
• Supports Valkey, File, and Database backends
• Flexible configuration via env.php
• Simple service interface (CacheRepositoryInterface)
• Tested with Valkey, File, and DB cache

Configuration

Add a new cache frontend in your app/etc/env.php under the cache key:

Valkey

  'cache' => [
      'frontend' => [
          'parsistent' => [
              'id_prefix' => 'YOUR_PREFIX',
              'backend' => 'Magento\\Framework\\Cache\\Backend\\Redis',
              'backend_options' => [
                  'server' => 'VALKEY_HOST',
                  'database' => 'VALKEY_DB',
                  'port' => 'VALKEY_PORT',
                  'password' => '',
                  'compress_data' => '1',
                  'compression_lib' => '',
                  'use_lua' => '0',
                  'use_lua_on_gc' => '1'
              ]
          ]
      ]
  ],

File

  'cache' => [
      'frontend' => [
          'parsistent' => [
              'id_prefix' => 'YOUR_PREFIX',
              'backend' => 'Magento\\Framework\\Cache\\Backend\\File',
              'backend_options' => [
                  'cache_dir' => BP . '/var/cache/parsistent'
              ]
          ]
      ]
  ],

DB

  'cache' => [
      'frontend' => [
          'parsistent' => [
              'id_prefix' => 'YOUR_PREFIX',
              'backend' => 'Magento\\Framework\\Cache\\Backend\\Database',
              'backend_options' => [
                  'auto_create_tables' => true
              ]
          ]
      ]
  ],
