2011年底，Basho宣布停止对Luwak的支持，原因是该模块存在设计缺陷，导致分布式垃圾回收等问题。随后开发了一个全新的替代模块，此模块并未沿用Luwak的代码，并已在RiakCS上实现对大数据的支持。
很遗憾在2011年12月的时候，basho宣布[url=http://lists.basho.com/pipermail/riak-users_lists.basho.com/2011-December/006905.html]不再提供对luwak的支持[/url]。因为luwak有[url=http://lists.basho.com/pipermail/riak-users_lists.basho.com/2012-January/007170.html]设计缺陷[/url]。
[quote]From a technical standpoint, Luwak has some problems with the way in which files are chunked and manifest of those chunks is maintained.
Specifically, there is no good way of knowing when a given chunk is no longer in use, which creates a very thorny distributed garbage collection issue -- this is a fundamental design problem. In addition, the manifest of chunks does not properly handle situations where siblings of the manifest occur -- this is a significant implementation problem. These two issues, in particular, have led us to stop further development of Luwak and investigate other architectural approaches.
Above and beyond these technical issues, Luwak also doesn't solve a host of other problems that most people who want to store files in Riak encounter. We are in the process of building a complete solution for multi-tenancy file storage in Riak -- more info on that will be available next month.

一个替代模块在luwak终止后就在开发中，不过暂时不会开源。
新版的riak1.1依然可以使用luwak。

新模块和luwak没有任何关系，[url=http://lists.basho.com/pipermail/riak-users_lists.basho.com/2012-March/007967.html]不分享luwak的代码[/url]。
这个新的替代luwak的应用似乎已经实现了，在Riak CS上已经有[url=http://basho.com/products/riakcs/]提供5GB的大数据支持[/url]：
但是，到目前为止（2011-5-24），即使是在[url=http://basho.com/products/riak-overview/]riak企业版[/url]中还没有看到对Large Object Support的支持。
