Hi,
I am trying to expose Cache contents as an Odata API. I created the
Odata API using ASP.NET WebAPI. Inside the API implementation, I am
initializing Ignite in cache mode. Below is the method I am using to
retrieve a listing. I have 2 questions.

Thank you very much, I think this is very helpful for me.
I will change my compute code, and have a try.

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
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
Hi Guang,
Please show the source of the Person class. Does the 'age' field has

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
Hi,
DR is not supported out of the box in Ignite. However, GridGain provides
this functionality [1] as a part of there paid solution.

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

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?

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
Hi,
Your class is serialized with .NET BinaryFormatter, that's why SQL and LINQ
does not work [1].
To fix this, remove [Serializable] attribute and register the class in

var cfg = new IgniteConfiguration { BinaryConfiguration = new
BinaryConfiguration(typeof(MyModel) };
