Index class

Indicates that a field or a combination of fields should be indexed.

When applied to a field, that field alone will be indexed. When applied to a class, specify the columns that form a composite index.

Example (Field):

@Entity()
class User {
  @Index()
  @Column()
  late String email;
}

Example (Class - Composite):

@Entity()
@Index(name: 'idx_name_org', columns: ['name', 'orgId'])
class Person {
  @Column()
  late String name;
  @Column()
  late int orgId;
}
