phlib/hashstrategy
PHP hash strategy library including random, sorted, consistent, (*1)
, (*2)
Usage
Strategies
Values are added to an index with a specific weighting.
They are fetched according to the strategy and the hashing $key passed to get()., (*3)
- Consistent
- The same value(s) will always be returned for the given
$key.
- Weighting is used to increase the likelihood of a value being returned.
- Ordered
- Values are returned in order of decreasing weight.
- Values with the same weight are returned in the order added.
- Rand
- Values are picked randomly.
- Weighting is used to increase the likelihood of a value being returned.
$pool = new \Phlib\HashStrategy\Consistent();
$pool->add('one');
$pool->add('two');
$pool->add('three');
var_dump($pool->get('hello', 2));
ConfigPool
Combines available hash strategies with a set of configs to provide a direct way
to choose a config to use, for example choosing between a set of replicas., (*4)
$config = [
'server1' => ['hostname' => 'localhost', 'port' => 11211],
'server2' => ['hostname' => 'localhost', 'port' => 11212],
'server3' => ['hostname' => 'localhost', 'port' => 11213],
];
$hashStrategy = new \Phlib\HashStrategy\Consistent();
$pool = new \Phlib\HashStrategy\ConfigPool($config, $hashStrategy);
var_dump($pool->getManyConfigs('some key', 2));
