Code review comment for lp:~michael.nelson/launchpad/distro-series-difference-schema

Its surprising you don't want delete permissions. How does the derived distribution sync its changes up with its parent distribution?

Having a column called derived_series is confusing. The derived distro series is the child. Having it reference its parent via a column called derived_series seems wrong (The derived distro series is derived from the derived distro series, which is silly). What is the parent distribution of a derived distribution called anyway? Parent or is there some other term?

We should add an index on last_package_diff for garbage collection purposes.
