Java client for memcached spymemcached is a free, open source, simple, asynchronous, single-threaded memcached client written in Java. Here are some key features of "spymemcached": · Efficient storage of objects. General serializable objects are stored in their serialized form and optionally compressed if they meet criteria. Certain native objects are stored as tightly as possible (for example, a Date object generally consumes six bytes, and a Long can be anywhere from zero to eight bytes). · Resilient to server and network outages. In many cases, a client operation can be replayed against a server if it goes away and comes back. In cases where it can't, it will communicate that as well. An exponential backoff reconnect algorithm is applied when a memcached becomes unavailable, but asynchronous operations will queue up for the server to be applied when it comes back online. · Operations are asynchronous. It is possible to issue a store and continue processing without having to wait for that operation to finish. It is even possible to issue a get, do some further processing, check the result of the get and cancel it if it doesn't return fast enough. · There is only one thread for all processing. Regardless of the number of requests, threads using the client, or servers to which the client is connected, only one thread will ever be allocated to a given MemcachedClient. · Aggressively optimized. There are many optimizations that combine to provide high throughput. Requirements: · Java What's New in This Release: · Data decoding occurs in caller threads instead of IO thread. This should greatly improve performance by spreading out the load to more threads. (Kristian Eide) · MemcachedClientIF is added as an interface the client represents. This allows a client making use of the interface to mock the memcached interaction for better test coverage (Nelz) · Binary protocol stat support (protocol wasn't complete until October 19). · Async incr/decr with no default (Nick Brachet) · Whalin V1 transcoder (Boris Partensky) · Stats subcommands are now supported. · Removed delete with hold support (pulled from server in 1.3). · Miscellaneous bug fixes.
