He meant prescription.
In german Rezept is the word for both prescription and recipe (like in
cooking). Easy to confuse for us germans in english :)
Great. Now I don't know what he meant by prescription. :) Does it
matter? Might it as easily be foos and bars?
Christian,
Are you saying that you might need to access items
from an old database that aren't in the current snapshot?
Yes, prescription, sorry.
Yes, we need to look into different versions of the
continuously actualized data base. Like I did it now this creates
a slightly different, read-only data base every two weeks. Not that big deal
after I built the first DB today, we can probably live with < 300 MB
of database each version. (using zlibstorage)
It is just my optimizer brain, and the fact that the whole history of
the stuff
since 2012-01-01 fits into 125 MB of ZIP files, as delta-updates.
There must be a solution that utilizes this incremental update stuff nicely.
I wanted to use a versioned variant of btree, until I found out that even
the table lauout changed a bit three times, which creates a huge update.
cheers - chris
p.s.:
I needed to patch zlibstorage for Python 3.
Where can I put a pull request?
Jim

I don't understand this. What's a "recipe"? Why do you need to
consider old versions of the database?
