Hi Plonistas,

I'm about to start a project which will have a utility to store users data.

Since the data is small (just some numbers and strings) and there will be
hundreds and hundreds of them it doesn't make sense to create documents for
each of them.

I will start creating a persistent dictionary on the utility to store
everything, but I have a couple of questions:

- does it perform well enough to be kept forever (I'm thinking in millions
of data structures in the dictionary) on the ZODB or at some point it will
make sense to migrate the data outside (MySQL, Oracle ...)?

- if the previous is true (migrate outside), it's feasible to migrate the
data and adapt the utility while keeping the utility interface intact, so
the rest of the Plone system doesn't care about if the data is in ZODB or
MySQL?

I'm really interested more on the second question than the first, I can try
to make some performance tests myself if Plone starts to be slow. Any tip or
experience in such cases are really appreciate :)

Cheers,
