Hi Jason,
Without going into detail, Ignite Client node is the same as Server node
but can't keep data.
And, if I remember correctly, it can finish transactions itself, so it need
ability to store data to datastore.

I appreciate any help here as it basically means there's no way to guarantee
read-after-write consistency for events triggered off of a transaction
involving multiple caches, even if they access the data i
That worked. Thanks Pavel.

Interestingly, setting cache key affinity appears to resolve the issue,
however is there any way to avoid this for cases where there isn't a common
cache key on every item, such as foreign keys?

Affinity in the cluster is coupled to the topology. Any affinity based
processing requires a stable topology. Does Ignite guarantee that all nodes
are executing a transaction on the same affinity version? Please correct me
if I'm wrong but based on my observation in Race condition with partitio

Hi Matt,
I would recommend you to try using a static class instead of lambda for the
visitor implementation. Most likely it references some fields of the
enclosing class that should not be serialized. Generally, you should always
use static classes for anything that will be serialized, because it

I would also recommend to check that all required ports are opened on the
instances. By default Ignite uses 47500 for discovery and 47100 for all
other communications.

DR is not supported out of the box in Ignite. However, GridGain provides

Hi Bob,
Most likely these are distributed cache operations and since they are all
synchronous, you wait for each of them one by one. You can try to batch your
updates to improve performance or use data streamer [1]. It would be even
better if you used affinity collocation [2] and made sure that al

Hi,
First of all, you need not only the ignite-log4j jar, but the whole
ignite-log4j module with dependencies. Refer to [1] for details.
Also as far as I understand, the log4j did replaced the Java logger and you
got a different error. Is this right? If so, you should probably just
configure log4
I thought the purpose of using log4j was to avoid the steps in that link?
The link I included says "you can either add ignite-log4j module to the list
of the used jars so that Ignite would use Log4j as a logging subsystem, or
alter default Spark classpath as described here." Does "adding it to th
