Hi userx,
How do you start you client? You use a term IgniteClient, but it looks
like that you are using Ignite instance running in client mode. By
IgniteClient so-called "thin client" is assumed (java interface for
thin client has name "IgniteClient").

Thanks Ilya, I’ll upgrade and see if that works soon. Right now we’ve
switched to only using partitioned caches to avoid this issue. If it’s
something that isn’t fixed with 2.7 then I’ll create a bug and attach code
to reproduce it.
I’m really surprised that no one else is complaining about it.
Yes, you can replace an RDBMS of Ignite if Ignite APIs are sufficient -
usually, they are.

Gert, All,
That's not a peer-class-loading issue but rather the binary objects
limitation. It's impossible to change the *type* of an object field. You
can add new fields or remove existing ones. The same limitation applies to
SQL - now way to change the type in runtime. That latter should be

Hi Ilya,
Thanks for your response. I am attaching a session log from yesterday.
Please look into this and advise.
Notice that the call comes in at 8:56:59.952.
The app makes the update call at 8:37:00.021
After that there is a lot of Ignite chatter for about 12 sec..
The app starts logging

Hi,
I am trying to write some data to IgniteCache (PersistentMode) from a
Igniteclient to an IgniteServer. My IgniteClient is a simple java program
which is serving some requests. As a matter of fact, the IgniteClient is
instantiated lazily from a java program ( a server serving requests),
Hello!
Do you have a reproducer for this behavior? What do you mean by "different
server" here? Is there node loss? Do you have backups configured?

It is quite possible to configure services in the same Spring XML file as
the Ignite configuration.

Hi,
Yes, it's safe in case if rest (256-132) GB of RAM is enough for your system
working and other applications.
You have persistence, so your data will not be missed. Data region size sets
for every node and can be changed during node restart.
However, you should take an account to the next
Hi,
We are currently integrating Apache Ignite in our application to share
sessions in a cluster. At this point, we can successfully share sessions
between two servers, but there's one use case, which (seems) is not taken
care by Ignite.
In our application, we have a session object which is
As of now, what is the best way to use configuration files in Ignite services
(Node singleton)? Consider a cluster of 3 nodes
and each will have its own config file, where to put config files?

Hello!
If you plan on using Ignite features which use remote code execution, you
need to make sure that:
- You start your server nodes as .Net nodes (apacheignite/ignite is almost
certainly a Java node container)
- You need to either deploy your code on server nodes, or enable

Can you please provide logs from affected nodes? It's hard to say anything
specific otherwise.

Could you please attach additional logs from a coordinator node? An id of
that node you may notice in "Unable to await partitions release latch"

Also, it would be good to have logs from the client machine and from any
other server node in the cluster.

We’re actually looking into off-heap memory usage of ignite now, specifically
into the MaxDirectMemorySize needed.
So far it seems that MaxDirectMemorySize=256m should work. It may need to be
larger if you use non-default walSegmentSize.
Not limiting the direct memory size may result in
Hello.Sorry for so late to reply to you.
I think I reproduce this issue.Here are my reproduce steps:

2.create 2 tables with "template=replicated".
3.Insert data to 2 tables.
4.Open a connection to make a long time query targeting on first
Hi Jose,
First of you refer to a slide about Data Center Replication, an
commercial feature of GridGain. Ignite does not provide such feature.
Also, SQL and Cache API could behave different.
You can check how Cache API shows itself in your experiments.
CacheAtomicityMode and PartitionLossPolicy
When the cluster loses all copies of a partition the behavior is defined by
PartitionLossPolicy. The current default is IGNORE which is indeed an AP rather
than CP option. You can set it to READ_WRITE_SAFE or READ_ONLY_SAFE to get the
CP behavior. I would also strongly advise to do so if you

Not quite. Actually, I am not aware that Ignite requires some special
tuning of MaxDirectMemorySize. If direct memory causes OOME then the
