I don't think we can help you further without looking at some SQL

What's the connection string for your driver? Does it point to a server

Do you happen to run this query on client or server node? Try running it on
a server node for a chance. Clients initialize cached lazily and yield a

Hello!
When you run out of disk space, the Ignite node will stop functioning
normally, and your underlying PDS storage may become corrupted as well.
Thus it is recommended to avoid running out of disk space. This is not in

Hello!
Can you please run your app with JFR configured to record object
allocation, to see where it actually happens, and share some results?
Thanks,

Hello!
I guess it has to write all the data to disk. After 'alter table logging'
returns, you are guaranteed consistency on this table, meaning all of its
pages have to be persisted to disk. Obviously, it may take a lot of time if
you have many gigabytes to flush.

Hello!
Looks like a network timeout, probably caused by firewall between two
nodes, imparting their communication.
You can try updating to 2.9 and enabling communication via discovery.

Hello!
Nothing obviously wrong but it still seems to me that you're stretching it
too far.
Maybe you need to rethink your cache entry granularity (put more stuff in
the entry to make it self-contained) or use some kind of message queue.

Even with unpaired connections you need communication ports available in
both directions, unless you enable communication via discovery feature.

Hello!
Then you need to implement your own AffinityFunction by subclassing
RendezvousAffinityFunction.

Hello!
You can also use cache.withExpiryPolicy() to adjust that on the fly since
it's really a property of data.

Hello!
Why not, if it fixes the issue for you. Then you can try 2.9.0 once it is
out.
Unfortunately, a small snippet of server log is not sufficient, complete
log is needed. I can already spot some communication problems, though.

Hello!
You can just set clientReconnectEnabled to false. Then, if it is out of
topology, just start a new one to make sure you have a fresh start.
Not sure about other events. Maybe handle ACTIVATED/DEACTIVATED?

Hello!
I don't think so. Node can reconnect to a *different* cluster, or it may be
disconnected for a while and return to the same cluster. For client node,
segmented/disconnected difference is not relevant. Neither it is for server
node, in fact.

Hello!
I think you may need to write a custom affinity function for your use case,
which will confine every cache to a single primary node.

Hello!
How often do you create or drop tables? Minor version of 255 suggests a lot
of operations.
Can you share logs for your nodes prior to that error?

How many caches do you have? How often are they created?

frequently? I advise against it, caches should be long-lived for optimal
performance and decreased risk of running into issues like this one.

Hello!
I guess you will have to set it on all nodes in cluster, including client.
Also, 60s may be too long - maybe your network will start closing
connections earlier than that.
