Hmm, B-Trees and B+-Trees both can have variable length keys. I'll accept an assertion that MySQL index B-trees cannot - but we should be precise here, because its not a global limitation. That said, our DB design basically needs to take into account the union of limitations of all target DB platforms, so we do still need to cater for this. -Rob -- Robert Collins <rbtcoll...@hp.com> Distinguished Technologist HP Converged Cloud _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
