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. -- ,------------------------------------------------. | Dr. Tommaso Cucinotta <t.c...@ss...> | >------------------------------------------------< !
