Thanks I understand now. So if I asked you to build a data structure for the ZODB that can do insertions at a rate comparable to Postgres on high volumes, do you think that it can be done? If so, would it not be worth investing time and money into this? If not, why not? -- Roché Compaan Upfront Systems http://www.upfrontsystems.co.za _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
