Using hash functions for file storage?

I think this is what microsoft has done in SQL Server 2008 with FILESTREAM storage. It allows storage of BLOB data inside of SQL Server, but allows you to access the files directly off the disk, which gives you kick-ass performance Microsoft released a whitepaper on managing unstructured data that you may be interested in. THere's also an MSDN article describing FILESTREAM as well as the pros & cons of file storage & whether to BLOB or not to BLOB.

United States Patent 5742807 deals with this freepatentsonline.com/5742807.html Systems and methods for managing a plurality of electronically stored documents in an open document repository employ a one-way hash function to compute a hash for the stored documents as an indexing link. A document management index maps an attribute of an original document stored in the repository to the hash and the document. A hash-to-location index maps the hash to an address location of the document in a file system of the repository.

The attribute points to the hash which then points to the location for linking the attribute to the location.

This sort of sounds like sharding, but I am probably missing the subtleties. And equally I don't see many articles on it - a few on highscalability.com.

Chris Kimpton This would be called indexing. Sharding or partitioning is more about how to split a file.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
