Note that the entity has a property named id of type String.The default serialization mechanism used in CassandraTemplate (which backs the repository support) regards properties named id as being the row ID.
Controls whether migrations are numbered with serial integers or with timestamps. The default is true, to use timestamps, which are preferred if there are multiple developers working on the same application.
When deploying an application with multiple replicas, old (pre-Rails7.1) replicas will not be able to deserialize BigDecimal arguments from thisserializer. Therefore, this setting should only be enabled after all replicashave been successfully upgraded to Rails 7.1.
persister: specifies a custom ClassPersister. The persister attribute lets you customize the persistence strategy used for the class. You can, for example, specify your own subclass of org.hibernate.persister.EntityPersister, or you can even provide a completely new implementation of the interface org.hibernate.persister.ClassPersister that implements, for example, persistence via stored procedure calls, serialization to flat files or LDAP. See org.hibernate.test.CustomPersister for a simple example of "persistence" to a Hashtable.
JPA support property mapping of all basic types supported by Hibernate (all basic Java types , their respective wrappers and serializable classes). Hibernate Annotations supports out of the box enum type mapping either into a ordinal column (saving the enum ordinal) or a string based column (saving the enum string representation): the persistence representation, defaulted to ordinal, can be overridden through the @Enumerated annotation as shown in the note property example.
The property-ref attribute should only be used for mapping legacy data where a foreign key refers to a unique key of the associated table other than the primary key. This is a complicated and confusing relational model. For example, if the Product class had a unique serial number that is not the primary key. The unique attribute controls Hibernate's DDL generation with the SchemaExport tool.
Maps serializable Java types to an appropriate SQL binary type. You can also indicate the Hibernate type serializable with the name of a serializable Java class or interface that does not default to a basic type. 2b1af7f3a8
