[aaron-collier]

Query Resource (ID, Version) from Metadata Persistence Layer

• If Version exists / was provided:
  • Query DynamoDB resources table for id == ID, version == Version
  • Save response map[string]*dynamoAttribute to GenericResource map (i.e. map[string]interface{})
  • if no records are returned from Dynamo:
    • return a Resource Not Found error to client
  • if a record is found from Dynamo:
    • Save response map[string]*dynamoAttribute to GenericResource map (i.e. map[string]interface{})
    • Return GenericResource to Resource
• If Version is null / was not provided:
  • Query DynamoDB resources table for id == ID && currentVersion == true
  • if no records are returned from Dynamo:
    • return a Resource Not Found error to client
  • if a record is found from Dynamo:
    • Save response map[string]*dynamoAttribute to GenericResource map (i.e. map[string]interface{})
• Return GenericResource to Resource
