PHP Class MatthiasMullie\Scrapbook\Scale\Shard

Pass the individual KeyValueStore objects that compose the cache server pool into this constructor how you want the data to be sharded. The cache data will be sharded over them according to the order they were in when they were passed into this constructor (so make sure to always keep the order the same) The sharding is spread evenly and all cache servers will roughly receive the same amount of cache keys. If some servers are bigger than others, you can offset this by adding the KeyValueStore object more than once. Data can even be sharded among different adapters: one server in the shard pool can be Redis while another can be Memcached. Not sure why you would even want that, but you could!
