Use class inheritance for driver in case we need something other than
sqlite as time goes on.
SQLite is only 10% larger than the custom format used with osdk. When
compressed the SQLite manifest only fractionally larger than osdk. The
time it takes to generate and process is about 2x longer. However, the
benefit we get from using common contructs (sqlite) and tracking and
changing the manifest schema is enough for me to think this is right
way to proceed.
To generate a manifest with 2^24 objects (64TB disk) run:
tools/generate_manifest.py --backupsize 64000 --manifest /pathtosave/manifest
This will generate a 809MB file
