 Okay, so let's start, because it's very late and the last day of another summit, so I assume we have less people, and especially given recently, products like Zuckerer and other small products are losing results and focus, attention, so it makes sense. So firstly, I'm Felon, Felon Wang. I worked for Zuckerer for, I think, years, but to be honest, last cycle, the rocky cycle, I was not really active. I was working on Magnum and Kubernetes stuff, but I think I know very much for Zuckerer. So I know the work the team has done for last release. Just in case you're in the right room, Zuckerer is a messaging service of OpenStike, and for now I'm still thinking like the service like Zuckerer designed it, I'll show those service are still very important service for IceLayer because you have done a lot of things on top of Kubernetes, but you still want to get some service like messaging service or database service from the IceLayer. You don't want to maintain a messaging service on your Kubernetes cluster because it doesn't make sense. So currently, Zuckerer can support multi-tenant, that's for sure, and you can consume the queue service or the notification service from where the RESTful API and it has a very good, very simple architecture. Currently it can support both notification service and the queue service. So you can find the same thing on AWS for SQS and IceLayer. But I think you can only see the pop-up, the notification service on Google Cloud. On either, I think it's just named method bus or something like that, but it's very similar. So this is the architecture of Zuckerer. So there is a transport layer. Currently the transport is just an HTTP implementation and on top of that, it can support WebSocket and Whiskey. So with WebSocket, you can just get better performance compared with the traditional Whiskey HTTP approach. And for backend, currently we can support MongoDB, the very stable backend and Redis. And if you don't want to use any in-memory database, you can just use Swift. So for the feature and enhancements, we have done in Roque is firstly, we can support different format for client ID. So when you use Docker to consume the message from a queue, as a client, you have to specify your client ID to different USF with all the other client. So for the client ID, as before we can only use a traditional UUID, but currently you can use a different format. But you have to limitize the minimum characters and the maximum characters in the configuration file. And currently we can support the queue filter when listing the queue. And the checksum function for message body for better security. And oh yeah, we add three new reserved metadata in queue response body. That's for that letter queue and I can't remember the other two, but those feature has been done before, but we just need to add those metadata in this release. And the last one is send email subscription by Zucker because currently the only driver we can support for notification is send email. We can support like SMS or the other mobile notification because resource and yeah, whatever reasons. As before, we just use a third party command line to send the email, but now we are just using Python built-in email sending lip to send the subscription. So first then, we do have some things we would like to do. The first one, actually those things are on the list for quite a long time. The first one is we would like to introduce the topic as first class standalone results for notification because currently the notification service is fully tatted with the queue, the queue service. We would like to just like SQS and SNS, we would like to have a separated first class resource named topic just for notification. So when you want to subscribe, currently you have to subscribe a queue, but actually the queue is just a name. We would like to give it a topic. So when you want to receive a notification, you want to receive the notification from a topic, you subscribe not a queue. And another feature we would like to do is delete a message with claim ID. To claim ID, if you don't understand the mechanism of soccer, so the claim ID is really like a handler for the message you just claimed. So for example, when there is many clients listening a queue, client A just grabbed the message from the queue and just means claim, I'm claiming the message. With that case, the client B can't claim the message. So currently we would like to support a feature. User can use the claim ID to delete the message instead of just delete the message by the message ID or the queue. So it's a very good, very important feature we want to do. And another one is remove the pull group totally. Currently the pull group is useless and we would like to remove it as soon as possible. I think there's lots to release. Hopefully we can get it done. And another one is the queue metadata just like the other service in OpenStack. In Docker we are using a very complicated, not very complicated, it's very flat JSON and it's very strict to store the queue metadata. But we are adding more and more new features into Docker. So that metadata, that very flat JSON is getting complicated because for example, you have to add, for one feature, you may have to add many key for that feature. So it's getting messed. So that's the one we would like to introduce probably another resource, a dedicated resource to store the queue metadata. So for Stan, it's wrong order. So that's basically the focus for Rocky. I think currently we're still focused on the scalability and the user experience. And to balance we're still trying to get more adoption. As far as I know, currently there is only one customer in China named Qinhua Tongfang. They're using Dockerize notification service and Rackspace deployed a very, very old Docker version, but I don't think they're using it animal. So yeah, that's it. I don't know why you guys are here to join this session, but just in case, I think just like most of the other small service in the OpenStack community, Docker needs some help and need some more adoptions for Docker to help Docker improve. So it's, yeah, like we have discussed many times in the mailing list, it's just like a chicken egg problem, missing adoption. So we're missing feedback and without feedback we can't get it better. If it's not good, no adoption. So yeah, I think that's all. Any questions? No?
