Yes, you are right.

Hi,
We run a ignite cluster in kubernetes. We currently deploy our containerised
java code which uses xml to configure ignite nodes and start them. We use
Kubernetes Discovery for service discovery.
I want to do automatic cluster activation by defining baseline topology
using control.sh script
Thanks Dmitry

I don't think that there is a way to do it for nested objects,
unfortunately.
In that case, I think that you need to update your configuration [1]
Hi Alex,
I cannot get it to reproduce in my local environment yet. I will get back to
you with thread dumps as soon as I encounter this issue again.

Yes, that is correct.

If I am not mistaken, SQL tables cannot contain nested objects.
Apache Ignite SQL engine allows executing SQL queries of nested fields. In
case, a cache was configured via
Fixed it! I needed to put my thread to sleep while the query was open, like
this:
try (QueryCursor> cur = cityCache.query(qry)) {
// Iterating over existing data stored in cache.
for (Cache.Entry e : cur)
System.out.println("key=" + e.getKey() + ", val=" + e.getValue());
boolean done =
So can I add a field to a nested object dynamically (without restarting the
cluster) by using annotations?

Hi,
Unfortunately, in your environment, you can't stop the node without losing
the data. To stop one node safety you require at least one backup.

We've run into a problem recently where it appears our cache is deadlocking
during loading. What I mean by "loading" is that we start up a new cluster
in AWS, unconnected to any existing cluster, and then shove a bunch of data
into it from Kafka. During this process it's not taking any significant
Hi,
I don't think this feature requires any change in the SQL API.
When we create a cache, even if the value object contains a nested object, the
fields in the nested object can be mapped to columns in the table. Now we can
do this using QueryEntity, for example,
QueryEntity personEntity =
Hi,
All existing options of control.sh tool you can see here:
https://apacheignite.readme.io/docs/baseline-topology#section-cluster-activation-tool
To connect to some host and port you can use --host --port options (default
values 127.0.0.1 and 11211).
In case if you started the ignite in
Hi,
It depends on how complex your service would be. Considering that you're
going to use some HTTP server to process your REST queries, I would go for
the first approach and scale that HTTP server with AWS.

To accelerate *existing* Cassandra deployments because Cassandra's
in-memory options are not as good as Ignite.
If it's a brand new application, then I would use Ignite persistence from
the very beginning. Here is you can
I can see from the docs for IgniteConfiguration that some properties

Hi,
Looks like you’re performing a cache operation (invoke()) from a StreamReceiver
– this is not allowed.

Issue is still there in 2.5.0
Steps to reproduce:

2) start load testing on client nodes
3) stop server 1
4) start server 1
5) stop server 1 again when rebalancing is in progress

Hi Vishwas,
Where your kubernetes cluster is located? Google Cloud, Openshift or
somewhere else?
I've checked your service account configs (with role and binding) on Google
Cloud. It works well. Maybe the problem in your deployment file or in
changes related to docker image.
Here are the steps
