Subject maximum number of files on 1GB heap memory?
Date Mon, 02 Oct 2006 01:55:49 GMT

I measured inode memory usage.
It uses about 70 ~ 100byte per one file.
This means that NameNode can serve only 10 million files.
(1GB memory / 100 bytes = 10,737,418 files)
 
In general, Web search engine has over 100 million files.
Is there any other way handling many files?
