I'm using DURUS and my BerkeleyDB backend as a GIS repository. I store
tiled maps in the storage. I have about 50000 maps, of 500Kbytes each.
It works great. But since the images are stored compressed (PNG), I
would like to avoid the zlib inherent compression in Durus, for
performance reasons.

The issue are not the "permanent" maps but the temporal ones, like "on
the fly" maps with tracks layered over them, and things like that. I
would rather prefer to not compress an already compressed PNG generated
file.

Any "documented" option?.

I would like to be able to configure that, object by object. I'm aware
of "WRITE_COMPRESSED_STATE_PICKLES" attribute in "serialize.py", but I
would like to have a garantee of forward compatibility with future Durus
releases.

Thanks.
