Call an operation on all deployed remote services

[Joan Pujol <jo...@gmail.com>]

Hi,

Is there a way that I can call a remote service method in all of the
nodes where the service is deployed?

A lot of thanks in advance.

Thank you very much Pavel.
I will check both possibilities. In that case I'm not concerned a lot
about performance, because it's not for normal operation.
It's just a way to retrieve some information on running services to
catch some information in case of problems.

Cheers,

Hi, there is no such method.

I suggest using IgniteCompute.broadcast - it is the way to invoke some code
on multiple nodes simultaneously.

If you absolutely have to do this with services:
1. Call IgniteServices.serviceDescriptors
2. Find the right service in the resulting collection
3. Iterate over ServiceDescriptor.topologySnapshot
4. Obtain a service proxy for every node from 3:
ignite.services(ignite.cluster().forNodeId(uuid)).serviceProxy(...)
5. Invoke the method on every proxy

I don't recommend this though - not a right thing to do, and perf would not
be good.

Pavel
