Re: [WANTED]: contribute to blogs

[Ian Luo]

Agree. People claim the work but later they may busy on other stuff. We
should not let this fact block the work to be done. We should reclaim it
after wait for them for a certain period. 2 weeks looks to me reasonable.

-Ian.

I see. You may need to point us the code location so that we could discuss

Great! I also think extensibility is very important because most companies may 
already have their own authorization&authentication system inside, allowing 
them to easily legacy that system can be important.

Re: [DISCUSS] Dubbo Community Annual Report

It has been a significiant year for Dubbo, I can feel the community grew a lot 
in many dimensions. It would be great if there’s some summarized statistics to

I noticed you have raised a PR trying to make these two filters work in an

Re: ConsistentHash LoadBalance中的解释：缺省只对第一个参数进行Hash运算是什么意思？

[徐靖峰]

Hi all

I don’t think that ConsistentHashLoadBalancer should only load balance by the 
method param, maybe more configuration can provide to the user to achieve more 
type of dynamic hash parameters, such as hash by the requestIp, more request 
param.

Re: ConsistentHash LoadBalance中的解释：缺省只对第一个参数进行Hash运算是什么意思？

[Jason Joo]

hi, moe

I think what you mention is like "ip_hash" in NGINX or some other.

ConsistentHashLB is hashed by parameters because a same logic will just act the 
same under the same parameters (which we call it reenterability). Adding other 
parameters will break it.

While DUBBO provides the ability extending load balancers which makes it 
possible to implement kinds of balancers like ip_hash, app_version_hash or 
others.

best regards,

Jason

self introduction

[Daniela Morais]

Hello,

My name is Daniela and I'm a software engineer from Sao Paulo! As a Java 
enthusiast, I've used Apache's Projects for years such as Tomcat, Ant, and 
Maven and I always wanted to contribute. I've been developing microservices 
with Spring Boot so I thought that Dubbo will be a great opportunity to start 
to contribute.

I'm studying CS and I read some issues in Jira about GSoC 2019 
(https://issues.apache.org/jira/browse/DUBBO-33 
) and I want to improve my 
acknowledgment in those technologies (reactive architecture, load balancer, 
service mesh etc.) also.

I’d like to contribute a small commit so I look forward to working on this 
issue: https://github.com/apache/incubator-dubbo/issues/2984 


Thanks

Re: ConsistentHash LoadBalance中的解释：缺省只对第一个参数进行Hash运算是什么意思？

[徐靖峰]

Hi, Jason

I know that the default logic of ConsistentHash LoadBalance is hashed by 
parameters, and dubbo provide the configuration

  to config the hash params

 to config virtual nodes

My opinion is Dubbo can extend the hash key, not only the request method 
params. 

IP consistent hash is a such common requirement while Dubbo’s existing 
extension don’t include it, there is no need to let the users extend by 
themselves,
 
A little change for Consistent Hash LoadBalance will support such function.

Re: ConsistentHash LoadBalance中的解释：缺省只对第一个参数进行Hash运算是什么意思？

Hi Kitito:

If the user chooses ConsistentHashLoadBalance, indicate the user wants to load 
balance 
through the runtime parameters and expects remote calls with the same parameter 
values 
to fall on the same server. After the introduction of IP, this load balancing 
strategy will be disrupted.

Thanks,
Xiaobo
