libspymemcached-java - 2.12.3+dfsg-3 main

Spymemcached is a simple, asynchronous, single-threaded memcached client
written in Java, featuring:
.
* 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.
