How to get all Redis keys in cache in Laravel

Question

The caching facade in Laravel doesn't seem to allow you to get all keys currently cached in Redis.

I want to create an endpoint so that I can retrieve this information and know if my entries are working properly.

I tried using the Redis facade without success using the following commands and their respective errors

Redis::keys("*");

"Cannot use 'KEYS' with redis-cluster."


Redis::scan("cursor");

"Cannot use 'SCAN' with redis-cluster."

Answer 1

In Redis and cluster, if you have many keys, it is recommended to scan instead of keys. However, you should use it correctly. Try this approach.

use Illuminate\Support\Facades\Redis;

$cursor = '0'; // Start with initial cursor

do {
    // Scan for keys with current cursor
    list($cursor, $keys) = Redis::scan($cursor);

    foreach ($keys as $key) {
      echo "Key: $key\n";
   }
} while ($cursor !== '0'); // Continue scanning until cursor is '0'
