Ignite Service Grid
I am seeking some guidance about Ignite Service Grid.
We have a cluster of standalone Ignite data nodes. Connecting to the data
nodes, we have several Spring Boot applications each launching an Ignite
client node.
One of the Spring Boot applications creates Continuous Queries in Ignite.
These queries are invoked when certain Ignite caches are updated. This
appears to be working well.
Now we would like to implement some Ignite services - but not sure how to
proceed. We want to be able to invoke the services from any of the Spring
Boot client nodes, and from the continuous queries. We have tried having
one of the Spring Boot apps start an Ignite service node in addition to its
Ignite client node, but we get errors - but we're not sure that's the right
way to do it anyway.
We've been trying to follow this code in github (
https://github.com/dmagda/MicroServicesExample) but it doesn't really apply
to our case.
If you could point me to some realistic examples, that would be very
helpful.
Thanks!

Hello!
> Caused by: java.lang.ClassNotFoundException: com.domain.ignite.NodeFilter
What's up with this class? Is it available on service node? On other nodes?
Is version the same?

James, this can be resolved by either putting all the classes which are
required by your Service in the lib folder of ignite or enable peer class
loading. See [1] for peer class loading
[1] peer-class-loading
<https://apacheignite.readme.io/docs/zero-deployment#peer-class-loading>

We haven't even gotten a service node started properly. It is unclear if we
can do what we want with just 1 service node, or what a correct
architecture looks like.
Do we even need a service node at all? Can one of the client nodes support
running these services? If we need a service node, can it work if the rest
of our nodes use peer class loading?
Sorry - lots of questions about how to even begin

James, can you show us how you are trying to invoke the services from
continuous queries and spring boot as well?
