org.hibernate.reactive.id.impl

Class TableReactiveIdentifierGenerator

java.lang.Object

org.hibernate.reactive.id.impl.BlockingIdentifierGenerator

org.hibernate.reactive.id.impl.TableReactiveIdentifierGenerator

All Implemented Interfaces:

org.hibernate.id.Configurable, ReactiveIdentifierGenerator<java.lang.Long>

Direct Known Subclasses:

EmulatedSequenceReactiveIdentifierGenerator

public class TableReactiveIdentifierGenerator
extends BlockingIdentifierGenerator
implements org.hibernate.id.Configurable

Support for JPA's TableGenerator. Persistence is managed via a table which may hold multiple rows distinguished by a "segment" column value.

This implementation supports block allocation, but does not guarantee that generated identifiers are sequential.
