When a mapping requires a discriminator column an index should be created for that column
Description
In mongodb, for example, the following mapping:
1
2
3
4
5
@Entity
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "type")
public abstract class BigEvent implements Serializable {
}should create the following index (or something similar):
1
2
3
4
5
6
7
8
9
10
11
12
> db.BigEvent.getIndexes()
[
...
{
"v" : 1,
"key" : {
"type" : 1
},
"name" : "type_idx",
"ns" : "ogm_test_database.BigEvent"
}
]This should also happen with the deafult column (DTYPE column).
We should skip this step if a user has defined an index for the that column.
