>
> The {{servicecomponentdesiredstate}} table currently uses a compound PK based
> off of the cluster ID, service name, and component name. There are several
> problems with this approach:
> - Primary Keys should be data that's not part of the business logic of the
> system and not subject to be changed potentially (as strings are).
> - Other tables referencing the {{servicecomponentdesiredstate}} table would
> now need knowledge of cluster/service/component in order to make the correct
> FK association. This leads to extra data being tracked as well as data
> duplication.
> - Some databases, such as SQL Server, have problems with the indexing of
> compound PKs and may lead to deadlocks when querying and updating
> concurrently.
> We should change this table so that it uses a simple PK for referencing. FK
> relationships as they exist today can still be maintained as long as a
> {{UNIQUE}} constraint is placed on the table. We should:
> - Add a {{UNIQUE}} constraint to the former PK columns
> - Add an {{INDEX}} to the former PK columns
