Hi!
You can always use node filter to control where the cache is, I am not
sure if there is a way to control distribution though, I guess it might
be possible to use affinity keys and some kind of custom affinity
function that is able to distribute the keys depending on some custom
criteria,
Hi,
When SQL is executed, does ignite always scan only primary partitions of
all available nodes in cluster irrespective of cache mode partitioned or
replicated?
Thanks ,

Robert,
Could you please describe your use case? There several options that might
suit your needs.

Normally, Apache Ignite distribute data equally to nodes
How can I control this distribution?
I want to distribute more data to some nodes, and less data to other nodes
I also want to choose node to store cache
Thank you!!

Sri,
That's wrong to assume that the Ignite thin client is the only way to
access data stored in AWS or other cloud environments. The problems you are
experiencing are caused by the fact that your application is running on the
laptop while the cluster (server nodes) is within an AWS network.

Folks, does anybody have any experience with Striim or ready to research?

It might be an option for change-data-capture scenarios from Ignite
clusters (with and without persistence) to other stores like RDBMS or
Cassandra.

Hi,
What is the application doing while you are changing the topology? Is the
cluster under the load?
Generally, we've added critical failure handlers in the latest version of
Ignite and the message reported is printed out by them:

Hi Cihan,
Is there any reason why you cannot separate applications from Ignite as a
store/database? The embedded mode makes sense for low-latency use cases
while the standard client-server deployment option is better in terms of
manageability, scalability:

Next Tuesday I'll be in NY conducting in-memory computing essentials

stay and have a couple of beers/sodas discussing
Is it possible this is somehow causing the issue of the node stopping?

Thanks for the info, Ilya!
Do you think it would have any actual risk to use PartitionLossPolicy.IGNORE
with my configuration? Because as I understand the data is fully replicated on
each node, so it cannot really lose a particular partition; or do I
misunderstand?
Is there a ticket/link where
Hello!
You will soon be able to use topology auto-adjust. Until then, I guess you
will have to fix topology on entry of every node.

Hello!
I start ignite-client but it never does anything, and in thread dump I
don't see any relevant threads.
Can you perhaps make the error more apparent? I have trouble understanding
your scenario.
You can start client node (by setting cfg.clientMode=true) to avoid having
cache data locally.
Hello!
I have noticed that you have READ_COMMITTED isolation when reading. It will
doubtlessly lead to situation when you read value from TXN-1 to set1 while
TXN is in progress, and then will read value from TXN to set2 because it is
committed already.
Don't you see it as a problem?

FULL OUTER JOIN is not supported as it is not supported in H2 [1]

Hi,
I have a case where I'm trying to use Ignite (embedded i.e.:
Ignition.getOrStart(igniteConfiguration) called in a Spring bean definition) in
a multi-node Spring Boot application with active-active setup. My goal is to
utilize Ignite as a shared, atomic, and persistent key-value store.

I am giving the syntax as :
SELECT * FROM person Outer join city ON person.city_id = city.city_id
Same query works well with inner ,left ,right join .
Please correct me if i am doing something wrong.
P.S.
Both tables have index over city_id column

Hi Hemambara,
I rewrote my example in form of a junit test [1]. And I suppose that
it should pass to make the feature useful. Could please check it and
tell me if my understanding is wrong. I tried this test with proposed
fix and without it. Result was the same.
