Harry hi guys from our community meeting before we jump into agenda I, see new faces on the call. It's Manish, it's Daniel and I. Guess your salmon right yeah.

D

B

D

Know how to switch it? No.

B

That that's fine! That's fine!.

D

B

Can start learning surly, that's gonna.

C

B

You guys wanna sure why you're here why you joined you. Of course you can say no and don't share, but if you'd like you're welcome to do it.

E

Okay, I can't give it a start. My name is Tanya Malbec I'm working for BP for the British oil company and I'm being the chief architect for all things integration there. So we are currently driving a big API program internally, but I think we need to get this to the next epoch. I'm a messaging person right, I have a very strong messaging background and I always said: hey API is a non-technical right and we need to find also by to document and discover and share.

E

Our API is, as we have internally for all things messaging and that's why I'm quite interested in this journey to see how we can leverage ASA gate the I-44 this, because one thing we currently doing is be- is basically to what I would call democratize IT in BP, so basically leverage a lot of people consuming data streams, event streams, whatever data read and we need to publish this data assets, certainly and I- think that's a good way, because we have always some background with mule soft and the way we document basically web-based api's and I think it's basic, a good fit to two leverages.

C

Also welcome quick, quick, quick question: are you using Rundle currently, because you said you were using.

E

Yes, both I think we have basically I think two flavors right. One is where we will trying to force the contract first approach, where we're really trying to use Ramlal, because we have all the two links, all the power of the platform. And then we have there's again a kind of a big hello.

E

We have a big kind of more software engineering community which are probably more code first driven right and that we are still leveraging open, API or swagger to basically draft the contract after the fact also thanks.

D

So maybe I'm next yeah I found how to rename me and I'm cementing issue from the system's company part of DHT, a comb yeah and some time ago we start movement of our texture to micro services and micro service approach, and also, of course, the idea to use event-driven architecture principle. So they are looking to implement Kafka. You know infrastructure and as one of approach to implement API first is we found a sink API and found it's useful standard for us.

C

A

Yeah so yeah, so my name is Manish Kumar and working for blini and I have a 5 plus year experience with new soft and of community and I. Also I don't work directly with rules up, but a general shop investor I used to participate in meeting with a product team to provide high-level feedback and yeah I'm, currently working as a associate architect with one of the pharmaceutical company and yeah due to kovat.

A

We have a lot of work to do and, apart from that, I'm hoping from this community how we can leverage a trammel fragment and everything from soap to achieve a sink and even divine architecture, yeah and I hope closely working with you guys, I mean from the community perspective and from the learning yeah. So that's great too part of this community as.

C

Well, looking forward to work together, yes thanks yeah and.

B

For us, it's so so cool that every talk every thought every call we have different faces, some meeting services yeah.

B

So looking from the agenda perspective, there's only one item, I added today after quick conversation on the general channel with Simon, and it's about the the Java templates that Simon works at the moment. So the question was about me and I'm, totally, not technical guy in Java. That can be straight here, but basically the topic is about. Is there any like to do those two templates that we have like the the spring boot and the ordered a spring cloud.

B

If they exclude each other or actually they can there I mean at the end they are fundamentally different and there can be two templates.

B

And because I don't know, those two technologies so would be awesome if, like maybe from stress score or you Jonathan, because like from the like high level, I think they are totally different and they because different technologies are used under the hood. And why not having both. But do we have both developers.

F

So once again,.

G

I can I can address I. Think I can address the question. This is Jonathan, so I think the answer is that they're, they are fundamentally different. I mean there's, there's multiple different within the Spring Framework, multiple different ways to interact with different asynchronous resources in kind of different styles. So the spring cloud stream, one that you know I, think I think the commonality would be is maybe the object model definition.

G

But then you know the actual generation of the application interfaces are going to be different between the two, so I think it makes sense to leave them separate.

F

Though they also solved two completely different use cases right, one is a low-level interaction with with Kafka with some spring magic around, while the other one is that the spring cloud is more about integration and being able to reuse, Kafka and being cloud with other modules.

G

Correct yeah, like the spring cloud streams, one obviously is developed by solace, and so you know spring cloud provides a facade around different implementations, solace, conquer rabbit, etc.

G

There's also, you know: Google pub/sub, the other one looks a little bit more Kafka specific, and then you know I think that in the future there's even even going to essentially be another one. That's around using you know the spring integration with spring JMS. That would support all the different JMS providers as well, so I think I think they'll always be sort of multiple different spring. You know options because there's so many different options within the framework.

G

D

You yeah I, see the in general I agree. It was just a small concern about as I approach, because yeah I just small view to the court of spinning cloud template and yeah. It's also generated model by schema. It's also have some work with, of course, publish and subscribe and yeah.

G

D

Both templates have some some parts in the common, at least as a model generation, but yeah from big perspective. It's two different to to merge together, yeah yeah.

G

Again, I, don't I don't disagree that the models you know I mean in general, a model you know that's using JSON and Java is probably going to use Jackson and Jackson annotations and like that, should be able to be plugged into any java application. That's you know, sending and receiving you know, json messages, so you know. Maybe the discussion is, is how do we? How do we kind of create a more common object model generator versus the application level? You know spring hot streams versus different other. You know pieces of java in spring framework components.

F

So it's about how we can modernize the resolution right to get a benefit on colleges.

G

Yeah modularized, specifically the object model generation, because I think I think the object model generation should be common even outside of Spring Framework. To more you know, other yo like oh you just want to use. Maybe you just want to generate the object model because you're gonna write, you know some other. You know maybe you're writing JMS code, so you still want to use the object model. That's generated by you know that comes from the async API specification that uses Jackson so that you know you can easily serialize and deserialize.

G

Your events I think you know that should be common across all the different Java code. Generators. That's just my opinion.

D

There was 40.

C

I'm sharing the link with you here know why zoom.

H

C

Making it look like a league, but so we already have an instant for that. It's called Java project duration, and so the idea that we are considering for in a and it's an hour roadmap for this year to make these things like it not only for Java but for any language to make object. Generations like strats and go classes in Java, and you know several different languages- we might choose to go for quick type.

C

Some quick type is a library it's linking there on the user, and this library allows you to generate from JSON schema definition. It allows you to generate Rogers printers with Jackson those tracks, typescript objects or any interfaces, and all this stuff. So yeah just want to make the comment here that we're gonna address it and it should be like straightforward right so from that and plate. You might be able to do that. The way I imagine this is from the template.

C

You you say: please generate the the poacher here right in this file and you don't have to worry about anything else. Obviously, that will be like kind of magic. That's always cool to have this kind of magic if the default works for you, but also to be somehow customizable.

C

So this process of generating produce or any other objects and in other languages it would it's gonna, be included for sure it's something that we have in the road so say yeah. For now. We know that it's duplicated job on on the Java spring template and in the spring clouds strings template it's like all duplicated, but yeah.

G

Likely we're gonna.

C

Start cleaning soon, all these kill duplications right that we've we've been detective lately.

B

So we better q12 so little for all languages than just Java.

B

Any other questions or comments, this topic may.

G

Be one question I have is how come? Is there no way that we can make use of existing like the swagger open, API work, because it seems like we're kind of copying a lot of what they do.

D

C

Oh so yeah just quick responses. The word is that the swagger people deal is written in Java and I would generate this in the GS we sure can make use. We can port their code with no GS with a lot of patience, but it's certainly possible right, but we found this library. That's basically doing that right. So this this libraries is basically doing this. This job, it's generating the the models for you in any language, so so yeah and.

G

It's no GS, perfect.

C

Right, that's actually one of the migrating or reporting the code from swagger was one of the first options. The other options was as well in the beginning like okay, so that's migrated the generator to Java, so we already have that. But since none of us is a Java programmer here, I know how to code in Java but I suck at it. So so yeah.

C

We that's why we chose this direction and luckily we found this this library that makes it easy for for us to generate code and only to generate the models on the under language right. So we should be fine. I guess also that just let me add, I'm chatting lightly with the smart bear faults the guys behind behind the swagger, and maybe we can do some kind of cooperation there.

C

So yeah I'll check.

F

Do you have anything in the in the roadmap to support one of the standard used by, for example, Google pops up or Kafka, because they deliberate that you that you post there is a code generation that goes from one adjacent schema towards something in in in Java code, but most of the most of the streaming platforms out there use April or protocol.

A

C

I think I think it should be. It should be possible right, like it should be fairly easy. I would say famous that's words to have to add this feature to this library, to quick type to generate from JSON schema generate something on on forget the neck on protobuf, or something like this. Actually, if I call correctly I think they have something, maybe in any case I think generating protobuf transition schema is it should be straightforward?

C

The other way around it's, not that straightforward, but but yeah I think we should definitely explore that that option as well, but I, think it's gonna all depend on on. You faults in the community right, so we are community driven. So if we get a lot of requests from, you know Java with protobuf and/or, a bro with Kafka and Java, depending on how we sense or how we measure the community requesting certain features on the under code. Generators will will start prior.

C

This is prioritizing them as we go right because, right now the the myriad of languages frameworks and message formats, like average, is a schema protocol that that we have in front of us is like a trillion writes like.

G

Trillion combinations.

C

Yeah, it all depends, I mean it all also depends on the contributions from the community, of course like if you, if you think that this is something that would be valuable for you and then others I'm happy to to help anyone with this, like anyone that wants to jump into implementing these code generators or these features of the cut generator I mean I'm.

G

Saying I am happy, but we are.

C

Happy actually I was like well, maybe Lucas. Now it's not happy, but but but yeah. If that answers your questions, it's actually we have a road map that says double down on, kill generators. It's super generic I know it has to be because we don't really know what people are going to demand. So it's like we're at some point in this year, we're gonna start investing Harding mortgage generators or improving the ones that we have to be better and only bad bad.

C

What does it mean we'll define it once once we have this task in front of us right right now is like it could be anything.

G

C

We have millions of calculator spending, so I hope this helps and and again this and start your own right now, just to make it clear. You might see ourselves in right now or in the past future in the next week's I'm apologizing in advance, for what we're doing now, but we're trying to make the parser the JavaScript parser, which is the one that the generator uses and the generator both libraries we're trying to make both libraries reach the first stable person right so so we're doing a lot of breaking changes right without.

H

C

Consideration, like you, might we're gonna we're going to be breaking a lot, because if we are serious and actually there's a disclaimer there like be careful by with relying in this library in production because we're making breaking changes and it's that stable yet so our first priority will be to make the parser at the generator stable. So we can build on top of that right.

C

So yeah, sorry in advance for the next several weeks.

B

And additional comments.

B

Ok, so just say: follow up on what, on what front sets about breaking changes so um we're trying to make it like Moore's much smoother, because now we are doing this automated releases and we're making sure that T boo requests, that's verging thats merged and triggers release. It has proper description, but what's breaking broken in a given in a given release like today, we released a paper, sir, with new version where, for example, there's a small breaking change in our sanding, so yeah just an addition.

B

Any other questions from your site.

C

Yeah questions and requests, or just if you want to insult us or something like you guys, have doing a pretty bad job. I hate you. What.

B

Can't even turn off recording for a second yeah.

C

Exactly like, if you want to insult at.

C

Lucas, maybe mentioning a little bit the status of the conference.

B

Yeah so remember that we have this conference next week's Wednesday. The schedule is out. A few sponsors showed up also a few communities tweet about us and share news in their company websites. So it looks good there's also when you go to the conference site, there's already a link to a YouTube stream at which you can set a reminder if you want to have a some automated reminder for the event, because, as you know, this conference is it's free, so there's no way to sign up for the conference.

B

It's just gonna be just streamed our life to achieve and the at the moment were kind of exploring because we got three sponsors, so we have some money to spend on marketing.

B

So if you have contacted some super experienced marketing person that played with Twitter ads, because we would like to try Twitter adverts, Twitter's Twitter ads first so and they and this marketing person wants to contribute open source project.

B

Please help us in contact, because we're gonna now explore first with Twitter ads, put some budget on it and see what it how it helps with increasing the traffic to the website.

B

Also, if you have better ideas, ideas like I was recently thinking about stack overflow, us or something like this, then yeah feel free to share some good tips and tricks here. Yeah.

C

Even if it's just I don't know something that you you know people are doing, or if you can, you know strategies people are following like, for instance, will leave just share today, a technique of creating 20 little ads by little. It means cheap ads right, so 20, cheap ads and measured them and in different regions and different with different text, images and measure which ones are working well and then, depending on the ones that work the best.

C

You invest the rest of the money on two or three of them right, like the best that the ones that perform the best I've never thought about it. To be honest, like I, think it could be great I think it's. It might be even better if we had time, but we have only one week, so we don't have much time to play with it and measure so yeah.

C

If you have, if you know someone that knows about it and would like to I, don't know just give us an advice, quick advice: it doesn't have to be more than a few words or quick call or five minutes will be super super clear.

C

So yeah because we're not expert marketing experts, a buy, is actually video content expert, not system marketing. That's it's not marketing expert either.

A

A

But I really like the idea from the way you've created, YouTube, promo and and the content was quite interesting to watch. You know it's quite exciting. I would say it's really nice, which.

C

One, do you mean the the promo video exactly yes, yes, I love it and.

A

The line you have added that from the favorite current I'm.

A

Supposed to post over LinkedIn, because I'm too active in England I can't see much activity from async appealing but I, don't know. Yeah.

C

We we try to schedule the same things we schedule for Twitter. We schedule them for for LinkedIn, so I don't know, maybe yeah I don't know, maybe it's just because we don't spend so much time, but the other at least the scanning staff is, is post to Twitter, irritating yeah cool folks.

C

So is there anything else on the agenda? Lucas, no.

B

There was just one topic and yeah the conference topic. I, don't have anything specific.

C

C

For maybe not for you, but for people watching this video afterwards, if you're present in the conference, remember that you have to send us the video by Thursday yeah, that's another thing that I would like to clarify that the the the conference or the way we are trying to organize the conference, to make it more recently to network failures. Is that everyone, every presenter free records, the talk and we will be so the will be joining live with us. Then we'll introduce the top and we will start streaming the talk.

C

The video that recorded video during the during the the presentation, the speaker will be able to be on the chat replying to your questions. She doesn't have to wait until the end of the talk and, and also maybe, if there's time at the end of the talk, they will join again live to answer some questions like right as well, instead of written so yeah.

C

That's why I was saying that please send the video as if you watching this, we're sending a bunch of emails to to the presenters, but just want to make sure that the conference is resilient. Enough to network failures from.

G

C

Side right, we don't want to go, live with the conference and suddenly there's a network failure on the side of the presenter and then they cannot present so so yeah.

B

But I've heard that we are probably too protective here, because I will read the read lesson recently that states, for example, they invested now like the government or someone invested so much in the internet quality of the ice piece, because they assume that the traffic will increase. So they invested a lot now recently and si Furtick quality connection got even better yeah, but nothing prevents your router from crossing.

C

So yeah, so that's why anyway, I mean: if we have to go live we can, we can give, we can always go live, but that would be like we'll try to do our best.

A

Yeah so I mean just I. Have one question: I'd bukas me in science lab that there is no need to do registration for these I mean event. I would say so how about your tracking the number of participant? Do we have some limitation on the participant.

C

A

C

Youtube tells you how many participants with the livestream and there's no limitation. If we can be there, 40 million people.

A

B

It's gonna be YouTube views and then we're gonna compare it to the visits to the website to see if it's matching or but causa.

C

Also, don't forget that VBS will be so the livestream will. The video of the live stream will remain there on YouTube, so even the first, let's say the first month. This will start getting more and more views from people who couldn't join the live stream or they didn't know about it. Yeah then they find out after the latter type the conference, and they want to watch it afterwards. So so yeah, it's an asynchronous conference.

C

B

That we also plan to invest some some amount of of these posts for money to the promotion after the conference. Yeah.

A

C

It's crazy yeah, we don't know I mean it depends on how many things organising an online conference is for sure, organizing.

C

Regular conference right case it has less hedges. It has the problem with livestream right with network issues, but that's it that's. It only is that you can have basically I.

B

Think, thanks change. You can reach much more people right, yeah.

C

C

Yeah, but you cannot have beer with your colonies, I mean you can, but you have to pay for the beer.

C

Cool folks, any further questions or topics you want to cover.

A

So plan make I distantly joined this community and I just wanted to start how I think works from the Bills of perspective and not only from the user perspective but like including dremel fragment how to generate fragment for a sink and how can I learn much more from this community or from you guys. So how can I start this? You know I I involved with this community from last one month, I would say, but I don't know from there in what push start.

A

C

A

You can, if you can help me that I can write a blog I. Can you know I can because I have a very big community in South worldwide and I am reading so community worldwide. So no I wanted other folks to involve in that.

C

Regard regarding muse of integration, this KPI, it's still being built so their.

G

C

Of this currently working on their their own solution and not hide in this I'm helping them build their solution sure. So it's a it's great, but it's not there. Yet it's not it's not I, don't think, there's even a date for the launch. Yet the only thing I coul show you a little bit more is about the usage with Randall data types. So right now, it's possible to use Randall, take the types inside a sync, API and you'll get it. You can get the same benefits of using Jason skew right.

C

So you will not you zoom out with her noticing.

G

Any difference right.

C

So if you have, for instance, if you have your REST API is defined with rattle in one side and you have a bunch of data types defined right.

G

C

Want to reuse these data types in your say, for instance, Kafka, your event-driven architecture and you you don't want to redefine or Kathryn, could be whatever you don't want to redefine these data types you want to reuse. These ramble take the type definition you can use the known async API directly. You don't have to break it together right, so that's that's the only thing. That's possible right now, but I think so far aside from a product. That's that's it I mean that's.

C

That's the the common parts between the REST API world would say, event-driven architecture, swirl is it they both have in common some data types. Yes,.

A

C

Don't want to really find again and again in different formats right and maintain them in different formats and maintaining in sync.

C

That's why we we had the support for rebel right for people using problem for the drastic guys, so they can start reducing these data types.

A

C

A

I went through one blog, I, think it's written by you or who casts importer diamond segment for a sink one new hope. Yes, exactly yeah.

H

A

Okay and I, just I, was trying to implement we put two months back. I became very impatient one of the biggest client how to implement this hmm Aseem call by using the Blagh, but in real life, not implemented anything something some something called a sink because we've worked on synchronous and batch and material type of things, but I.

G

A

Want to implement in their life, at least from the user perspective, so that I can give a demo or presentation to to to the our team or or company or kleiner.

C

We can handle this of life. You want yes, yeah yeah, that's just big me! So I, don't forget anybody.

A

H

C

H

C

B

And for the questions like Jonas you're with us again surprise, surprise yeah,.

H

Yeah, no I don't have any questions.

B

So I think we can three-two-one finish the call thanks a lot for joining, especially old new faces, hope, you're staying longer with us.

H

B

You have further questions, feel free to ask, of course, on slug, bye and see you guys.

A

Yeah. Thank you thanks a lot for joining me.

C

A
