Hello,

there is no Redis clone implemented in Java as far as I know. Btw
being Redis easily compilable in most posix systems, and with a
networking API, what would be the goal of such a project?

Cheers,
Salvatore

This cannot be compared to redis, but do you know of it? I just saw it on dzone a few days ago.

Why do you need redis-server in Java?

Redis is designed for high-performance in-memory key-value lookup, if it is implement in Java, it will lose its benefits.

In my project, I need to use Java client to connect redis. In unit testing, we wrote mock client for simplicity, it won't impact anything related to C. In smoke testing, we create a testing redis service, and use JRedis to connect to it. For redis-server binary you used in this smoke test, you need to make sure which version of java you are using, and make sure the binary is in the same page.

Maybe it is helpful to you.

I agree that the interest is rather limited for most users.

I guess some corporate people could be interested by a Java version
to embed it into a J2EE compliant container (such as jboss or
weblogic).
Some academic people may want to use it as a testbed to develop
plugins,
experimental new features, a threaded Redis using lock-free data
structures, etc ... Finally, some others may think that using a
higher-level language is a way to attract more developers to an
open-source project.

Usually, when people propose a Java clone of some existing robust and
efficient C/C++ program, it is for one of these reasons.

Regarding performance, you may be interested by this link:

While slower than the C version, this Java implementation of memcached
is not ridiculous, and actually quite usable.

Didier.

redis done in Java would have all sorts of Garbage Collection issues,
performance would be good for like an hour, and then CHAOS
