For below code snippet, if exception occurs do I need to rollback the
transaction? Or closing the transaction takes care of it?
try (Transaction tx = transactions.txStart()) {
Integer hello = cache.get("Hello");
if (hello == 1)
cache.put("Hello", 11);
cache.put("World", 2

Hello Ilya
Can you provide some links/examples on how to use
ignite.binary().type(field-name)?
thanks.

Hello Juili,
This exception might happen if KubernetesIPFinder cannot connect a
Kubernetes API server. It uses this address:

Hi Pavel,
Thanks for confirming.
I have modified this particular subsystem to use Compute functions to
transit the data I was moving via messaging (this is a case where data
needs to move to the logic, unfortunately), and to use the custom
WithExecutor(). So far it works pretty well :)
Thanks,
R
Raymond, I don't think there is a way to move IMessageListener.Invoke calls
from Ignite public thread pool to somewhere else. WithExecutor API is for
Compute only.

arrives from another node using IMessageListener
Possible
Hi,
I used ignite in version 2.7.6 (but I have also seen this behaviour on
other 2.7.x versions) and there aren't any near or local cache.
I expect that if I ask distributed cache about key which does not exist
then the miss metric will be incremented.

Hello!
I can see a lot of activity from your side, and ask you to participate in
debugging and development.
Please file tickets about the issues that you encounter and propose fixes.
I think you have as much expertise around writing security plugin as
anybody else.

Hello!
I don't think there is any utility, but you can use
ignite.binary().type(string) to clarify field types.

Thanks Ilya.
Is there any utility that returns the (java) field types for the query
entity defined caches? I don't want to have to map jdbc types to java types.

This fails when the security plugin is enabled. When I remove the security
plugin, the query goes through.
With the security plugin enabled, it hangs at :
GridReduceQueryExecutor - on awaitallReplies method. Attached screenshot of
thread , when it hangs.
Steps I take :
1. Start my server with 2.
Hello!
You can use JDBC's DatabaseMetaData for that.

Hi,
We are using ignite to run join queries which are handwritten by user.
We have got a security threat using ignite as ignite is using h2 with admin
privilieges.
Which means user can execute any kind of system functions like filewrite,
fileread etc.
Is there a way to start ignite with a low p
Hello!
Apache Ignite has known limitations on the use of distributed SQL, namely
that there is just one reduce phase.
I'm not actually sure whether you have hit this exact one using this query.
Let's wait on feedback from SQL people (who are probably busy with their
Calcite affair), but of course
