Hello, If an object can be serialized into a binary form, then Ignite will calculate its hash code during serialization and write it to the resulting binary array. Also, Ignite provides a custom implementation of the equals method for the binary object's comparison needs. This means that you do not need to override the `hashCode` and `equals` methods of your custom keys and values in order for them to be used in Ignite, unless they cannot be serialized into the binary form. For instance, objects of Externalizable type cannot be serialized into the binary form and require you to implement the hashCode and equals methods manually.
