ATTENTION! look here: class org.apache.ignite.IgniteCheckedException: Failed to deserialize object ...... com.dream11.watchlive.IgniteReconciliationCron$$Lambda$615/798682906
in the ignite guides https://ignite.apache.org/docs/latest/code-deployment/peer-class-loading they speak clearly: /When defining the classes listed above, we recommend that each class is created as either a separate class or inner static class and not as a lambda or anonymous inner class. Non-static inner classes are serialized together with its enclosing class. If some fields of the enclosing class cannot be serialized, you will get serialization exceptions./ So, also make sure that all fields are serializable. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
