This is an alternative memcached cache engine to the memcache engine shipped by default with cakePhp. Default one uses the memcache extension, whereas this one uses the memcached extension. (notice the d)
- Allow binary protocol
- Increment/Decrement a compressed key
- Uses igbinary for serialization (memcached has to be compiled with --enable-igbinary)
Igbinary is the big win of the memcached extension.
Igbinary is a drop in replacement for the standard php serializer. Instead of time and space consuming textual representation, igbinary stores php data structures in a compact binary form. Savings are significant when using memcached or similar memory based storages for serialized data. You can expect about 50% reduction in storage requirement and speed is at least on par with the standard PHP serializer. Specific numbers depend on your data, of course.
see https://github.com/phadej/igbinary
and some benchmark
Just drop the MemcachedEngine.php file in you app/Lib/Cache/Engine/ directory, and use $engine => 'Memcached' in your Cache::config.
Current version of the memcached extension (1.0.2), as well as the next beta (2.
0.0b2) implements a very basic getStats(), that doesn't allow retrieval of the list of keys stored in cache.
Each key is stored in another key in memcache when Cache::write() is called, that's read to extract all the keys. This implementation takes more place, but there's no other solution.
