DBM::Deep has something in it's README 
REAL-TIME COMPRESSION EXAMPLE
Here is a working example that uses the *Compress::Zlib* module to do
real-time compression / decompression of keys & values with DBM::Deep
Filters. Please visit
<http://search.cpan.org/search?module=Compress::Zlib> for more on
*Compress::Zlib*.

use DBM::Deep;
use Compress::Zlib;

my $db = new DBM::Deep(
file => "foo-compress.db",
filter_store_key => \&my_compress,
filter_store_value => \&my_compress,
filter_fetch_key => \&my_decompress,
filter_fetch_value => \&my_decompress,
);
