nosql - Cassandra是否适合存储文件？

Question

我正在开发一个php平台，该平台将大量使用我想到的图像，文档和任何文件格式，因此我想知道Cassandra是否是满足我的需求的理想选择。

如果没有，您能告诉我如何存储文件吗？我想继续使用cassandra，因为它具有容错功能，并且在节点之间使用自动复制。

感谢帮助。

从cassandra wiki，

Cassandra's public API is based on Thrift, which offers no streaming abilities 
any value written or fetched has to fit in memory. This is inherent to Thrift's 
design and is therefore unlikely to change. So adding large object support to
Cassandra would need a special API that manually split the large objects up 
into pieces. A potential approach is described in http://issues.apache.org/jira/browse/CASSANDRA-265.    
As a workaround in the meantime, you can manually split files into chunks of whatever 
size you are comfortable with -- at least one person is using 64MB -- and making a file correspond 
to a row, with the chunks as column values.

因此，如果文件大小小于10 MB，就可以了，只需确保限制文件大小，或将大文件分成几块即可。
