blocks|key|1586192|text|大约一年前，当我不得不使用memcached+java客户端时，spymemcached连接器被描述为一个具有更多功能的优化API。从那时起，memcached客户端已经发布了许多新版本，所以它可能值得一试。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1586193|FWIW间谍客户对我来说工作得很好。|1586194|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

<p>As of about a year ago, when I had to use a memcached java client, the spymemcached connector was described as an optimized API with more features. Since then there've been a number of new releases of the memcached client so it may be worth checking out.</p>

<p>FWIW the spy client has worked perfectly for me.</p>

<p>As the author of <a href="http://code.google.com/p/spymemcached/" rel="noreferrer">spymemcached</a>, I'm a bit biased, but I'd say it's mine for the following reasons:</p>

<h2>Designed from scratch to be non-blocking everywhere possible.</h2>

<p>When you ask for data, issue a set, etc... there's one tiny concurrent queue insertion and you get a Future to block on results (with some convenience methods for common cases like get).</p>

<h2>Optimized Aggressively</h2>

<p>You can read more on my <a href="http://code.google.com/p/spymemcached/wiki/Optimizations" rel="noreferrer">optimizations</a> page, but I do whole-application optimization.</p>

<p>I still do pretty well in micro-benchmarks, but to compare fairly against the other client, you have to contrive unrealistic usage patterns (for example, waiting for the response on every set operation or building locks around gets to keep them from doing packet optimization).</p>

<h2>Tested Obsessively</h2>

<p>I maintain a pretty rigorous test suite with <a href="http://dustin.github.com/java-memcached-client/emma/" rel="noreferrer">coverage reports</a> on every release.</p>

<p>Bugs still slip in, but they're usually pretty minor, and the client just keeps getting better.  :)</p>

<h2>Well Documented</h2>

<p>The <a href="http://code.google.com/p/spymemcached/wiki/Examples" rel="noreferrer">examples</a> page provides a quick introduction, but the <a href="http://dustin.github.com/java-memcached-client/apidocs/" rel="noreferrer">javadoc</a> goes into tremendous detail.</p>

<h2>Provides High-level Abstractions</h2>

<p>I've got a Map interface to the cache as well as a functional CAS abstraction.  Both binary and text support an incr-with-default mechanism (provided by the binary protocol, but rather tricky in text).</p>

<h2>Keeps up with the Specs</h2>

<p>I do a <a href="http://cloud.github.com/downloads/dustin/memcached/changelog.html" rel="noreferrer">lot of work</a> on the server itself, so I keep up with protocol changes.</p>

<p>I did the first binary protocol server implementations (both a test server and in memcached itself), and this was the first production-ready client to support it, and does so first-class.</p>

<p>I've also got support for several hash algorithms and node distribution algorithms, all of which are well-tested for every build.  You can do a stock ketama consistent hash, or a derivative using FNV-1 (or even java's native string hashing) if you want better performance.</p>


blocks|key|1371218|text|我一直在使用SpyMemcached，我不得不承认它是市面上最好的，有很多新的改进。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1371219|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]
