Primary key fields
Primary key fields can identify a record in case its _id value changes due to reindexing or reingestion. In the Info tab of the data model, select a combination of fields whose values create a unique combination for each record. You can also select just one field if that field has a unique value for each record. See
Creating entity tables.
To change these fields, the system user must have READ access to the index pattern of the entity table.
Adding or editing primary keys
When you have selected the primary key fields, from the action toolbar, click Save to save the fields to the data model.
Retry applying primary key fields
If the system reports an error with the primary key fields, click Update collections to retry applying the fields.
