[Openflow-dev] OpenFlow searching.

[Tommaso C. <ke...@ti...>]

Hi all,

I understand that OpenFlow uses the ZODB storage facility
in order to store permanent workflow data.

As I don't know how the ZODB works, I'm just wondering
about what could happen in case of a great number of
process instances going on in the system. Did you ever
test OpenFlow with some thousand of instances ?

As far as I can understand from a very fast look at the
code, the Catalog object inside openflow is sometimes
used to find objects. Is this a way of dealing with
the just cited issue ? If yes, what are the index-ed
items inside the catalog (process definition ids,
activity ids, ... ??).

Do you know what kind of transactionality model is enforced
within the ZODB (when used in the Zope default mode, I've read
you can put ZODB above an external DBMS) ?

Thanks, bye,

	T.
