For a very simple example of creating persistent objects, please see the seed method of SeedDatabase.java.
Apache Ignite（以下、Ignite）をはじめ、Apache Geode, Hazelcast等のような代表的なインメモリデータプラットフォームは、基本的にメモリ上にデータを持ち処理を行うが、億単位のレコード数になると、データの永続化を行う永続的ストレージ（Persistent Storage）の力を借りることも可能としている。. 図4． Apache Ignite In-Memory Data Fabric. 当然ながら、ローカルキャッシュと違って利用面のメリットが大きい。Ignite 1 を使うことでデータは遠隔ノード間で分散されるので、データ取得はローカルキャッシュよりは遅くなるが、次のような利点を享受できる。. When JPA isn’t enough, Hibernate OGM extends it with family-specific and product-specific options. That way, the power of the backend is at your fingertips. All that in a type-safe way.
