Strange, I've never seen consistent IDs collisions before. Are you using
Ignite persistence and what's your version? If you scroll to the end of
this paragraph, you'll find an explanation on how the IDs are generated:

Eugene,
Please share full logs from all the nodes and execution plan for the query.
That's what the community usually needs to help with troubleshooting. Also,
attach GC logs. Use these settings to gather them:
Hello,
Is it possible to set a nodeId when restarting a node? How is the id
generated?
Sometimes after the cluster crashes, when I restart a node I get the

Prasad,
To achieve the best performance, join criteria should be the same as
collocation criteria. E.g., if you join by userId, then userId should be
used as affinity key. Please learn more about distributed joins here:

Hello,
I have a medium cluster set up for testings - 3 x r4.8xlarge EC2 nodes. It
has persistence enabled, and zero backup.
- Full configs are attached.
- JVM settings are: JVM_OPTS="-Xms16g -Xmx64g -server -XX:+AggressiveOpts
-XX:MaxMetaspaceSize=256m -XX:+AlwaysPreTouch -XX:+UseG1GC
It is unclear what the intended semantics of using
IgniteCompute.affinityRun() when a subset of the grid was selected. From
reading the code, my current guess is IgniteCompute.affinityRun() will run
on the primary, regardless of whether only a subset of the grid was
specified.
In my case I
Super, that looks like the solution. Thank you so much for this. It's been so
difficult navigating without complete documentation. Will give it a whirl.

Hello!
I think you should be using
IgniteConfiguration cfg = Ignition.loadSpringBean(/* rel path, abs path or
url */ "server.xml", /* bean name */"grid.cfg");
TcpDiscoverySpi spi = new TcpDiscoverySpi();
spi.setAuthenticator(new CustomSecurityProcessor());
cfg.setDiscoverySpi( spi);
Hi Steve,
It is an interesting question. I am not aware of any development in this
direction. Perhaps, more experienced community members could tell more.
I think that it would be great to experiment around a topic disabling some
checks here and where. Then it worth to run some kind of benchmark

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

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

Can you please elaborate which settings you want to transfer to Java?

I am seeking some guidance about Ignite Service Grid.
We have a cluster of standalone Ignite data nodes. Connecting to the data

client node.
One of the Spring Boot applications creates Continuous Queries in Ignite.

Hello Danis,
Thanks for your reply, but SqlQuery is working fine, is there any
difference in P2P class loading mechanism between SqlQuery and ScanQuery?
Thanks

The client protocol doesn't imply P2P class loading.
So, you need to provide the implementation of the scan query on the server
side.
P2P class loading works only for regular nodes, server or client as well.

I managed to run the task every x seconds using an infinite loop
though. "deployClusterSingleton" was the key to make it work. Many thanks.

That didn't help because extended syntax is not for running task every x
seconds. It specifies the delay in seconds to run the task for first time
and number of times the task has to be executed.
