Old Content Show after updating the content using Memcache Api

Hello,

any news on this? We are using D10.2 with php8.1 and saving menu, or any admin settings changes do not clear memcached.

Thanks

Hai even we had this issue. And it took us a while to debug this issue. We did two things.

1) Made AWS elastic host into 2 nodes.
2) Then used those 2 nodes in settings.php

Below is the configuration code for the memcache.

$memcache_hosts = getenv('MEMCACHED_HOST') ?: 'memcached';
$memcache_port = getenv('MEMCACHE_PORT') ?: '11211';


// Shared Memcache server definition
$memcache_servers = [];
foreach (explode(',', $memcache_hosts) as $host) {
  $host = trim($host);
  if (!empty($host)) {
    $memcache_servers["{$host}:{$memcache_port}"] = 'default';
  }

if (getenv('ENV') == 'prod') {
  $config['config_split.config_split.local']['status'] = FALSE;
  $config['config_split.config_split.acceptance']['status'] = FALSE;
  $config['config_split.config_split.prod']['status'] = TRUE;

 //Memcache configs 
  $settings['memcache']['servers'] = $memcache_servers;
  $settings['memcache']['bins'] = ['default' => 'default'];
  $settings['memcache']['key_prefix'] = 'MigrationYorkshire';

  $settings['cache']['default'] = 'cache.backend.memcache';
  $settings['cache']['bins']['render'] = 'cache.backend.memcache';
  $settings['cache']['bins']['dynamic_page_cache'] = 'cache.backend.memcache';
  $settings['cache']['bins']['data'] = 'cache.backend.memcache';
  $settings['cache']['bins']['entity'] = 'cache.backend.memcache';
  $settings['cache']['bins']['menu'] = 'cache.backend.memcache';
  $settings['cache']['bins']['page'] = 'cache.backend.memcache';

  $settings['cache']['bins']['bootstrap'] = 'cache.backend.database';
  $settings['cache']['bins']['discovery'] = 'cache.backend.database';
  $settings['cache']['bins']['config'] = 'cache.backend.database';
  $settings['container_yamls'][] = DRUPAL_ROOT . '/sites/default/memcache.services.yml';
}
