Hello, We are building up an application where we use multiple zodb instances. Indexation is done using solr. zodb are served through zc.zodbwsgi. ZODB connections are set only on-demand, upon traversal. Each zodb has its intid local utility. Each object also has a uuid.
I have a zodb with global parameters objects on /params and distinct zodb as /foo /bar /baz and so on. Objects in a zodb may reference objects of the same zodb or of /params. I have two possible strategies : - either store uuid of referenced objects and retrieve objects from solr (which will give me a zodb name + intid of object) - either directly reference the objects of /params Of course second option seems better and more natural. I read http://svn.zope.org/ZODB/trunk/src/ZODB/tests/multidb.txt?rev=99605&view=markup and using pdb on databases = request.environ['zodb.connection'] I can see the zodb.databases map which is ok. I also know that _p_oid is unique and _p_jar handled for each object so I feel confident on this side. So before I dive into this, is this kind of cross-database reference used on production applications. Is there any-risk or any trick to be aware ? Thanks in advance for any comment :-) Alex _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org https://mail.zope.org/mailman/listinfo/zodb-dev
