Shiva,
Just to clarify, the peer class loading (p2p) is a global setting and can
be set to on/off for particular nodes.
As for your case, the client has to send a compute tasks or execute
p2p-enabled API first and after that a server which will be processing the
task/request will preloading missi

Hi,
I’ve reproduced this and have a fix – I guess it’ll be available with 2.8.
Meanwhile I can only suggest not to create indexes without an explicit name.

Thanks Ilya,
It works with runAsync.
(Question) Can you clarify why does it work on a single node well and when
going on two nodes it doesn't, and we get the exceptions? I was expecting it
also to be happening on one server node.

Hi Ilya,
The field apn_id is of type Long. I have been using the CacheJdbcPojoStore,
does that map the BinaryObjects to the database schema? or is it only for java
pojos? I have attached the xml I am using with the client.

caches had been evicted before I tried to iterate over caches. Thanks a lot

Hello!
I don't see any lengthy GC pauses yet one node were segmented. It is

retrying? Please attach logs if there is failure again.

Hello!
As a general principle you should avoid doing any blocking operations from
event handlers, which is precisely something that you are doing.
If you replace run() with runAsync() in your service impl, it will finish
all right with two ServerNode's.

I think that your CacheStore implementation is confused by nested fields or
binary object values (what is the type of apn_id?). Consider using
CacheJdbcBlobStoreFactory instead which will serialize value to one big

Hi,
Ignite supports only simple password authentication from the box. It doesn't
contain any complex rights access.
You can read more about it here:

In case if you require for authorization options you can implement the

Hi,
BinaryObject in C++ is not the same thing as in Java right now.
Currently C++ client do not support "BinaryObject" construction
