The statless design was developed in the experiment branch, the experiment shows advantage in removing the status synchronization, uuid mapping compared to the stateful design, and also fully reduce the coupling with OpenStack services like Nova, Cinder. The overhead query latency for resources also acceptable. It's time to move the statless design to the master branch BP: https://blueprints.launchpad.net/tricircle/+spec/implement-stateless Change-Id: I51bbb60dc07da5b2e79f25e02209aa2eb72711ac Signed-off-by: Chaoyi Huang <joehuang@huawei.com>
