Yes, unless you specify a different IgniteConfiguration#marshaller <https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/configuration/IgniteConfiguration.html#setMarshaller-org.apache.ignite.marshaller.Marshaller-> .

But BinaryObject lets you operate over objects without having the corresponding POJOs on your class path. Also by using BinaryObject you skip (de)serialization step, when performing put/get operations, so you may get better performance. > Is the a way to deserialize AvroFormat messages from kafka to ignite sink?
