databases like mongodb stores things.   You essentially store documents
that are quickly retrievable, and then the indexing on the document's data
is done in the application (and sometimes with another database).

Either way though it would be a shame for RPM to lose it's ACID properties.
  That said the world is moving to doing rollbacks through a filesystem
snapshot (which I just noted was in RHEL 7 today) so maybe ACID becomes far
less important.
