Thanks Vladimir Chernyi for your blog. That helped a lot in improving the
performance. I am converting the object to Binary Object before storing. This
doesn’t seem to be issue just when loading the data alone.
I have a scan query which also fails with same exception.
List<BinaryObject> cacheObjects = cache.withKeepBinary().query(new ScanQuery<>(
//filter for just Blade Enabled Users
new IgniteBiPredicate<String, BinaryObject>() {
@Override
public boolean apply(String s, BinaryObject binaryObject) {
return ((HashSet)
binaryObject.field("field1")).contains("34");
}
}),
// Transformer
new IgniteClosure<Cache.Entry<String, BinaryObject>, BinaryObject>() {
@Override
public BinaryObject apply(Cache.Entry<String, BinaryObject>
stringBinaryObjectEntry) {
return stringBinaryObjectEntry.getValue();
}
}).getAll();
Weirdest thing is that the classes seem to be loading on the cluster, only when
i modify something on the class. I can replicate it again when I start the
cluster wiping the data folder. It appears so that the grid deployer is not
deploying classes to the cluster until it sees that the class has changed , but
shouldn’t it deploy first time?.
Thanks,
Siva.

Hi Siva,
Thank you for reading my blog post. I have no idea what is the problem in your
case, just wanna share some experience.
I do not use any user POJOs on the remote nodes. Instead, I create POJO on the
thick client node, convert it in BinaryObject and change that object on the
remote node by object.toBuilder().setField().build(). I use key value API only.
So no class not found issues arise. Hope that helps

Hi,
We are trying to use ignite for the first time in our project. We are trying to
use ignite with persistence enabled.
Architecture is as follows.
SpringBoot 2.3 application (thick client ) tries to connect to apace ignite
cluster (3 nodes ) with persistence enabled and peer class loading enabled.
There seems to be a weird issue with peer class loading.
We are trying to load huge data following the same approach as here -
https://www.gridgain.com/resources/blog/how-fast-load-large-datasets-apache-ignite-using-key-value-api<https://clicktime.symantec.com/33sZ5STPWrhi61h4sP3SJYy6H2?u=https%3A%2F%2Fwww.gridgain.com%2Fresources%2Fblog%2Fhow-fast-load-large-datasets-apache-ignite-using-key-value-api>
Cache Configuration
cacheConfiguration.setName(CacheIdentifiers.USER_IGNITE_CACHE.toString());
cacheConfiguration.setIndexedTypes(String.class, IgniteUser1.class);
cacheConfiguration.setCacheMode(CacheMode.PARTITIONED);
cacheConfiguration.setStoreKeepBinary(true);
RendezvousAffinityFunction rendezvousAffinityFunction = new
RendezvousAffinityFunction();
rendezvousAffinityFunction.setPartitions(512);
cacheConfiguration.setBackups(1);
cacheConfiguration.setAffinity(rendezvousAffinityFunction);
Scenario 1.
Start the cluster --> activate the cluster --> start the thick client -->
Loading clients/ignite.cluster fails
Exception occured in adding the data javax.cache.CacheException: class
org.apache.ignite.IgniteCheckedException: Failed to resolve class name
[platformId=0, platform=Java, typeId=620850656]
Scenario 2.
Stop the Thick client , Rename the file from IgniteUser1 to IgniteUser and
restart the thick client , the classes are now copied to the cluster and works
fine.
I am not sure if there is an issue with grid deployment. Any help would be
appreciated.
Thanks,
Siva.
