Hello, I have a class "Invoice" with unique index on fields "month" and
"cardNumber".
I have another class "Item", that have many fields, plus "month" and
"cardNumber".
When I run the "Item" ETL, I need to create edges from "Invoice" to "Item",
but I cannot use the "joinFieldName" property with multiple fields.
I am trying the code below (and many other changes):
{ "edge": { "class": "HasItems",
"joinFieldName": "month,cardNumber",
"lookup": "Invoice.month, Invoice.cardNumber",
"direction": "in"
}
}
but it seems the ETL only allows single-field relationships.
Is that true?
Is there a way to create edges on such tables (multiple-fields key) during
ETL? If not, how to create the edges after the bulk load (with SQL)?
Thanks in advance,
JH
