Versioned binary files stored as deltas rather than as exact copies of files?

[Bob Kerfoot <bk...@dearborn.com>]

I am currently storing versionable .tgz files in my repository and the versions
are being created as expected as .bin files under
"/repositoryroot/version/blobs".


However the .bin file used to store each version of the binary is an exact
duplicate of the actual binary file being versioned rather than a delta
of the previous version and the current version.

Is there any way to have the the .bin files stored as deltas rather than as
exact copies of the binary being versioned?

Do you know whether there is currently delta based versioning for 
files of any kind in jackrabbit? Specifically, can text files and/or
any other non-binary file types be versioned as deltas in jackrabbit?
If not, might there be any plans to introduce this delta based 
versioning for text or other non-binary file types in the future?

Am I correct in understanding that this alternative way way of
storing blobs does not use deltas but rather just maintains a single 
copy of each unique blob and then uses pointer(s) to reference that 
single unique copy if a duplicate binary version of the file is 
entered into the repository?

Thanks again for your time.

hi,
currently there are not plans of implementing a smarter storing of
versioned content.
but we're thinking of an alternative way of storing blobs so
that every unique blob only gets stored once. so if the binary data
does not change from version to version, it would only get stored
once.
