Cassandra 适合存储文件吗？

发布于 2024-12-26 06:14:46 字数 163 浏览 5 评论 0原文

我正在开发一个 php 平台，该平台将大量使用图像、文档和我想到的任何文件格式，所以我想知道 Cassandra 是否是满足我需求的不错选择。

如果没有，你能告诉我应该如何存储文件吗？我想继续使用 cassandra，因为它具有容错能力并且在节点之间使用自动复制。

感谢您的帮助。

来自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.

所以如果您的文件< 10MB 应该没问题，只要确保限制文件大小，或将大文件分成块即可。

So if your files are < 10MB you should be fine, just make sure to limit the file size, or break large files up into chunks.
