File::HStore
rationale:
File::HStore by Alexandre Dulaunoy, is a similar module that
provides File::Hash based storage. However due to the nature of File
Hashing, File::HStore doesn't allow duplicates. If the same file is
stored a second time using File::HStore it transparently returns the
same hash it had returned last time without adding any new file in
storage due to inherent character of hash based storage, while this
is useful if a user doesn't want any duplicates occurring in a
storage, this apparently trivial difference is risky in the use case
where two processes upload a duplicate file to the store and both
process want to do file handling, only one of the processes will be
able to get a lock(deletion,manipulation etc.) on the file at a time
and if the first process deletes the file referred to by its ID, the
second process will never know what happened to the file it added.
Hence I wrote this module for a UUID based storage solution which
is not hostage to auto de-duping features of HStore. This module
returns a unique file id each time a file is uploaded even if its a
duplicate of existing file previously uploaded. This allows multiple
processes handling data from a common file dump to access the same
file. This module also expands on the Hstore to allow the user
flexibility of choosing the depth of storage to optimize the
performance for the users application. Depth of storage allows users
to make the balance between average "number of files in a folder"
and folder depth.
