Response Structure

(dict) –
- status (string) –
  
  The HTTP return code of the request. If the request succeeded, the code is 200. See Common error codes for DFE statistics request for a list of common errors.
  
  When invoking this operation in a Neptune cluster that has IAM authentication enabled, the IAM user or role making the request must have a policy attached that allows the neptune-db:GetStatisticsStatus IAM action in that cluster.
- payload (dict) –
  
  Statistics for RDF data.
  - autoCompute (boolean) –
    
    Indicates whether or not automatic statistics generation is enabled.
  - active (boolean) –
    
    Indicates whether or not DFE statistics generation is enabled at all.
  - statisticsId (string) –
    
    Reports the ID of the current statistics generation run. A value of -1 indicates that no statistics have been generated.
  - date (datetime) –
    
    The UTC time at which DFE statistics have most recently been generated.
  - note (string) –
    
    A note about problems in the case where statistics are invalid.
  - signatureInfo (dict) –
    
    A StatisticsSummary structure that contains:
    - signatureCount - The total number of signatures across all characteristic sets.
    - instanceCount - The total number of characteristic-set instances.
    - predicateCount - The total number of unique predicates.
    - signatureCount (integer) –
      
      The total number of signatures across all characteristic sets.
    - instanceCount (integer) –
      
      The total number of characteristic-set instances.
    - predicateCount (integer) –
      
      The total number of unique predicates.
