Hello, dear Ignite users & developers
I'm running an Ignite 2.6.0 cluster in k8s as a partitioned cache
(off-heap) with eviction policy. It all works great and handles around 100K
RPM in peaks (many thanks for the software!).
The problem I'm facing is that on cluster topology change, all
Hi,
We are using ignite to share in memory data across the spark jobs. .
I am using below configuration to set ignite offheap memory. I would like
to set it as 100 gb.
However when I print the node statistics using visor it shows offheap max
memory as 1 gb.
Please suggest.
Apache Ignite
The error means that there is no such class on classpath. Please check if
that's the case or not.
You can also provide your project and steps to reproduce the issue, I will
take a look then.

Hi,
We create a cache using SQL DDL syntax.
How can I configure Cassandra persistent store to the cache in .NET
application ?
It seems like default CacheConfiguration is automatically applied
internally in Java codes for SQL cache, so not able to load up Spring.XML
for that cache.
Here is
i have integrated a database with ignite and the generated project created
classes for the tables. If i try run Sql scan query execute over the cache

Hi, I am basically starting Ignite node through my Java project. When I run
the above specified code, I first run the ignite.sh from my remote server as
well.

Hi
Suppose I have two ignite caches and these two caches are collocated based
on a field using AffinityKemapped. Now if I configure same number of backups
for both the caches, do the backup copies also get collocated i.e backed up
on same nodes ?
For ex: one row of cache1 and one row from cache2
No, a new client will not receive these messages because they were sent on
previous topology version. (topology version changing after join/left any
node)
The messages will be sent only to current client nodes.

I opened the persistent storage cluster, version 2.3 as long as the boot
server and then activate the cluster when the client can be connected
directly, after upgrading to 2.6, after activation server cluster for the
first time the client connection complains, you then need to Deactive the
cluster
thanks,
When I want to send messages from server to client, it works
probably, there were a problem as you stated.
May I ask :
Let's say server send a messages to client ("hello")
When I create another client after seconds, minutes vs.. , this new client
will see this messages?
Same question for
Hi,
Could you please provide step by step instruction on how you upgrade the
cluster?
Please note that in case if you try to use the persistence then the
important feature that was added in 8.4 - baseline topology. A baseline
topology is a set of Ignite server nodes intended to store data. The
Hi,
Do you use the in-memory region for these caches or region with persistence?
What is your ignite version?

Hi,
Are you sure that server sends a message only after a client is joined to
topology?
Please, check that ClusterGroup clientNodes is not empty before sending a
message to the topic.

Hi,
PeerClassLoading is not working for classes which are part of a cache
configuration.
These classes (cache store implementations, eviction and expiry policies,
etc.) must be explicitly deployed on all server nodes.

Hi ,
I have a situation here . Whereby there is a cachestore adapter class for
cache read through in my code and I am starting the ignite cluster in
client mode.
I am connecting to ignite cache server on yarn . I have specified the server
to load peerclassloading and the same is enabled in
The problem with the Ignite version upgrading from 2.3 to 2.6 is that when
the Server side starts up, the client will report an error when connecting
to the Server side. The client must first stop activating the Server side,
then connect with the client once, and then reactivate the Server side
