esi / consistent-hash example snippets


use Esi\ConsistentHash;

$hash = new ConsistentHash();

// bulk add
$hash->addTargets(['cache-1', 'cache-2', 'cache-3']);

// simple lookup
$hash->lookup('object-a'); // "cache-1"
$hash->lookup('object-b'); // "cache-2"

// add and remove
$hash->addTarget('cache-4');
$hash->removeTarget('cache-1');

// lookup with next-best fallback (for redundant writes)
$hash->lookupList('object', 2); // ["cache-2", "cache-4"]

// remove cache-2, expect object to hash to cache-4
$hash->removeTarget('cache-2');
$hash->lookup('object'); // "cache-4"
