Hi!
You may get worse performance with a thin client compared to an ordinary
client because as the thin client works through an intermediary node, so
your request will always go to node A in your case and then it will be
handled there, a normal client would go straight to the node where the

Hello, I have 4 nodes for server node and I'd like to allocate 4G each node.
but I don't know how to calculate heap size set for each node of percentage.
what percentage is proper for node (JVM -Xmx) if I use only off-heap cache.
Is there any best practice for heap size for node?? or reference
Thanks Wesley, Alex. Attached is a snapshot of the client log. I don't see
anything on the ignite server side.
I am/was trying to do get data from a replicated cache.

Hi, thanks for the prompt response
We can have several of these caches, one for each query (is an exceptional
case but, with load, there can be several simultaneously) that is being
executed so we would like to preserve the persistence to take advantage of
the swapping in case the amount of memory
Hi,
Have you tried to put the temp cache into the different, non persisted,
memory region?
You can also try to use a node filter to control what nodes should store
the cache.

Hi Ignite team, We have a use case where a small portion of the dataset must
answer successive queries that could be relatively expensive. For this, we
create a temporary cache with that small subset of the dataset and operate
on that new cache. At the end of the process, that cache is destroyed.
Server 1 -> Let's say IP is X. Status is running.
Server 2 -> Let's say IP is Y. Status is not running. We stopped this node

Hello!
I have merged this fix to master.

Also wanted to mention that there is a working semaphore example available:

Hi,
In an older version there was an issue that caused this condition
https://issues.apache.org/jira/browse/IGNITE-8987
Send a reproducer, mention the version you are using, along with Ignite
logs(from both nodes) and a stack trace of both servers when this condition
occurs.

Hi, As Wesley mentioned, It’s quite difficult to say something specific about without the logs. As for the additional questions, can you explain, what Ignite API is being used? Is it a Compute API call or a regular cache GETs? It’s totally fine to spawn several user threads and access the server
Courtney,
This config should be enough
It will load the ML plugin and initialize model storage.
You can send me a reproducer and I'll take a look.
Thanks, Alex

It turned out if I inject a pause of 4-5 seconds, then the client
connection goes through.
Why the service grid requests go through immediately but the regular cache
access requires a pause from the time an ignite instance is acquired?
Subsequent calls are fast. The caches are replicated.

Does either client or server have any logs?
Thanks

I have a server and a client node, the latter running in tomcat. I get
connection refused if I try to connect to the server node from the client,
although the server shows the client has joined the cluster. I don't have a
problem running a service on the
