Hi 
 Sorry did not include the context when I replied 
 Has anyone been able to resolve this problem, cause I have it too on and
off 
In fact it sometimes happens just like that, e.g. I have been running my 
Ignite client and then stop it, and then it takes a while and run it again, 
and all by a sudden this error shows up. An that is the first thing that 
happens, and there is NOT a massive amount of load on Cassandra at that 
time. But I have also seen it when I hammer Ignite/Cassandra with 
updates/inserts. 

This is a deal-breaker for me, I need to understand how to fix this, cause 
having this in production is not an option.

Hi! 
I'm using the cassandra as persistence store for my caches and have one
issue by handling a huge data (via IgniteDataStreamer from kafka). 
Ignite Configuration: 
final IgniteConfiguration igniteConfiguration = new IgniteConfiguration(); 
        igniteConfiguration.setIgniteInstanceName("test"); 
        igniteConfiguration.setClientMode(true); 
        igniteConfiguration.setGridLogger(new Slf4jLogger()); 
        igniteConfiguration.setMetricsLogFrequency(0); 
        igniteConfiguration.setDiscoverySpi(configureTcpDiscoverySpi()); 
final BinaryConfiguration binaryConfiguration = new BinaryConfiguration(); 
        binaryConfiguration.setCompactFooter(false); 
        igniteConfiguration.setBinaryConfiguration(binaryConfiguration); 
        igniteConfiguration.setPeerClassLoadingEnabled(true); 
final MemoryPolicyConfiguration memoryPolicyConfiguration = new
MemoryPolicyConfiguration(); 
        memoryPolicyConfiguration.setName("3Gb_Region_Eviction"); 
        memoryPolicyConfiguration.setInitialSize(1024L * 1024L * 1024L); 
        memoryPolicyConfiguration.setMaxSize(3072L * 1024L * 1024L); 
       
memoryPolicyConfiguration.setPageEvictionMode(DataPageEvictionMode.RANDOM_2_LRU);
 
final MemoryConfiguration memoryConfiguration = new MemoryConfiguration(); 
        memoryConfiguration.setMemoryPolicies(memoryPolicyConfiguration); 
        igniteConfiguration.setMemoryConfiguration(memoryConfiguration); 

Cache configuration: 
final CacheConfiguration<String, BinaryObject> cacheConfiguration = new
CacheConfiguration<>(); 
        cacheConfiguration.setAtomicityMode(CacheAtomicityMode.ATOMIC); 
        cacheConfiguration.setStoreKeepBinary(true); 
        cacheConfiguration.setCacheMode(CacheMode.PARTITIONED); 
        cacheConfiguration.setBackups(0); 
        cacheConfiguration.setStatisticsEnabled(false); 
        cacheConfiguration.setName("TestCache"); 

        cacheConfiguration.setReadThrough(true); 
        cacheConfiguration.setWriteThrough(true); 

        cacheConfiguration.setWriteBehindEnabled(true); 
        cacheConfiguration.setWriteBehindFlushFrequency(10000); 
        cacheConfiguration.setWriteBehindFlushSize(0); 
        cacheConfiguration.setWriteBehindFlushThreadCount(2); 
        cacheConfiguration.setWriteBehindBatchSize(10000); 


        final CassandraCacheStoreFactory<String, BinaryObject>
cacheStoreFactory = new CassandraCacheStoreFactory<>(); 
        final DataSource dataSource = new DataSource(); 
        dataSource.setContactPoints(contactPoints); 
        dataSource.setReadConsistency("ONE"); 
        dataSource.setWriteConsistency("ONE"); 
        dataSource.setLoadBalancingPolicy(new TokenAwarePolicy(new
RoundRobinPolicy())); 
        cacheStoreFactory.setDataSource(dataSource); 

        final String CASSANDRA_PERSISTENCE = "<persistence keyspace=\"%s\"
table=\"%s\">" + 
                "<keyPersistence class=\"%s\" strategy=\"%s\"/>" + 
                "<valuePersistence class=\"%s\" strategy=\"%s\"/>" + 
                "</persistence>"; 
        final KeyValuePersistenceSettings settings = new
KeyValuePersistenceSettings( 
                String.format(CASSANDRA_PERSISTENCE, "test", "test_table", 
                        "java.lang.String", "PRIMITIVE", 
                        "org.apache.ignite.binary.BinaryObject", "BLOB")); 
        cacheStoreFactory.setPersistenceSettings(settings); 
        cacheConfiguration.setCacheStoreFactory(cacheStoreFactory); 

When application works some time (hour or more, may be less - from time to
time) I see this exceptions on the ignite nodes:

After this I have to restart the cluster and application or have
"transactions deadlock" message. 

And I checked: network is fine, no OOME in the ignite and cassandra
(cassandra logs don't say anything about it). I understand that this is
issue of persistence into cassandra but don't know how can I fix it. And
after some attempts ignite node is stopped. I tried to change write behind
parameters and disable it at all - but have the same issue. May be I have to
see in the other place? May be this is important - i use IgniteDataStreamer
for reading values from kafka (earlier I used the simple cache operations
and didn't have this problem at all). 

final IgniteDataStreamer<String, BinaryObject> streamer =
ignite.dataStreamer(callCache().getName()); 
streamer.autoFlushFrequency(5000); 
streamer.keepBinary(true); 
streamer.perNodeBufferSize(5120); 


And one more question about persistence settings. If I'm working with
BinaryObjects and ignite doesn't know about my class types, should I use
valuePersistence class =  "org.apache.ignite.binary.BinaryObject"? I did it
because peer class loading doesn't work for my own classes and I don't want
to add new jars into all ignite nodes and all my apps. 

Thanks for help!
