Gracefully unexporting/passivating the exported services
Dear experts,
We are using Dubbo for exporting our services to outside clients.
During the execution, we may have to switch some nodes into maintenance mode (for maintenance purposes of course), which means those nodes are not serving requests until they are switched back to normal mode.
Our question is: what is the recommended procedure to gracefully put an exported service into maintenance mode, without causing a perturbation on the client side, which may still maintain an open connection with the exported service?
Best regards
Tien Dat PHAN

Hi,
Indeed it is :p
I just wanted to double check with you if such implementation already exists :)
Thanks again
Best regards

Hi, tien
So far as I know there wasn't.
In my opinion it should not be complicated to implement similar function in such scenario.
So the road is under your feet, haha

Dear Jason,
Thank you for your interesting material.
This would answer the need of our use case.
Just a small question is: Does Dubbo provide a JAVA API for such QoS features?

Hi Tien
You can refer to QOS feature of DUBBO.
