Best practice for class versioning: marshaller error

Hi, I am running Ignite 2.3 using Cassandra as my persistence store. I got unmarshall error when a server node trying to unmarshall an object of old version from Cassandra. This is the scenario: 1. Object of ClassA (older version) is serialized and persisted into Cassandra 2.

Call to deployClusterSingleton blocked.

Hi, I encountered a scenario where my process was blocked at a call to deployClusterSingleton. IgniteServices svcs = ignite.services(); svcs.deployClusterSingleton(..., ...); Too bad that I didn't get the stack trace. I didn't specify any node filter. I was able to deploy the service upon

OptimizedMarshaller instead of BinaryMarshaller is used for ScanQuery

Hi, I have a cache of . I found that when I use a ScanQuery on that cache, result will be deserialized using OptimizedMarshaller; Ignite sends 'ordered' message using GridCacheQueryResonseEntry. Whereas if I use ContinousQuery, result will be deserialized using BinaryMarshaller. My problem

RE: Best practice for class versioning: marshaller error

Then I am confused with the exception I got. Please bear with me. I believe what happened was a client (with a new version of user class) trying to deserialize an old object (an old version of user class) from Continuous Query. This was what happened base on the log: 1. GridCacheIoManager

RE: Best practice for class versioning: marshaller error

Hi Dmitry, Thanks for your response! I want to confirm my understanding - If I disable compact footer and add your POJOs in BinaryConfiguration, I will be deserialize back the serialized object after I stop grid and removed the local files that hold the marshaller cache (I believe they are
