ContractKeys - what if one of the field part of the key needs to be updated?

[Vivek_Srivastava]

Whats the best practice around handling this kind of situation? Do we need to update all the contracts accordingly?

[bernhard]

In short: yes. Keys should be stable. I’d think of them like primary keys in relational databases. If you don’t have a stable key to hand, generate one like a uuid.
