If pub-#14505 number increase all the time, does it mean the public thread

Hi,
Thanks for looking. You need to run two instances of the reproducer. Let the
first run until you can see "Wait" on the console then run the second. For me
the second instance won't get past the Replace call in either 2.6 or 2.7.
It's using the default config with nothing else set up over an
Hi,
I'm working on a .Net Core (2+) application that uses Ignite. I've noticed some
odd behaviour and have narrowed it down to a Put or a Replace call hanging
after a PutAsync.
I started looking at the issue when one of our nodes was randomly logging a
possible starvation in striped pool warni
Thanks Val.
Is there a way I can verify this behavior - a way to query one node in
particular to see what data is on each node?

If I have something like:

I understand service grid does not have peer class loading, so we need to
provide any needed jars to the /libs directory of our Ignite nodes.
As we make changes to our service classes over time, those jars will also
need to change.
Can we do some kind of rolling deploy - bring down 1 node, update

Sorry - lots of questions about how to even begin

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.

Hello.
I am creating a Spring Boot application that gets objects from Kinesis and
uses ignite-spring-data to insert those objects into an Ignite cluster.
As objects are inserted, I want to take some action - specifically, inspect
the object being inserted, query Ignite for a related object and if

In Ignite implementation, schema is "PUBLIC" at beginning during runtime,

But I cannot figure out why my code get this exception.
I am running a local server with native persistence.

Nikolai,
What is "describe on update events and update the cache"? Can you describe
them in detail or provide a url?
For question 3, can I use grid service to do some computation? Which one has
a better performance - SQL or grid service?
Thanks,
James.

need to use a lot of
join to generate a set of data as a view like in traditional database. How
do I create a view in Ignite.
3. On the data in above view, I need to query again to do a lot of
computations such as "group by" to find a maximum value.
What is best approach in Ignite?
Than
following dummy question?
What is api for standard client-server? What is api to embed Ignite into my

I like to get some databse sql query benchmarks on ignite vs MySQL? Where
can I find a big database data?
