This value is assigned by the DB engine because is a \"autoincrement\" integer.\n\nclass StandardAttribute():\n    ...\n    id \u003d sa.Column(sa.BigInteger().with_variant(sa.Integer(), \u0027sqlite\u0027),\n                   primary_key\u003dTrue, autoincrement\u003dTrue)\n\nThis value is provided, during a transaction, when the transaction is flushed. That happens in the network DB creation in [1], at the end of this subtransaction context.\n\nIf this \"id\", when the transaction is committed, has been used and deleted, the \"id\" reference will fail. We need a retry method but I suggest to use oslo_db.api.wrap_db_retry [2]\n\n\n[1]https://github.com/openstack/neutron/blob/8d6c301301e33697fd4eb4d6de53f680b909a04d/neutron/db/db_base_plugin_v2.py#L401\n[2]We talked about using oslo_db to decorate DB operations https://bugs.launchpad.net/neutron/+bug/1887523","commit_id":"d57209bf7f9894d8a769a3c606359f30d951468b"}]}
