Serialization - sorokinigor/akka-persistence-hazelcast GitHub Wiki

The plugin uses Akka Serialization to serialize/deserialize journals' events and snapshots to/from Hazelcast.

Hazelcast's serialization facilities are not used for user data. Even though, internally, keys for events/snapshots are instances of DataSerializable, still, you do not need to configure Hazelcast serialization in order to use this plugin.
