        QuerySpatialCoverage (dict) –
        
        Provides insights into the spatial coverage of the query, including the table with sub-optimal (max) spatial pruning. This information can help you identify areas for improvement in your partitioning strategy to enhance spatial pruning.
        
        Max (dict) –
        
        Provides insights into the spatial coverage of the executed query and the table with the most inefficient spatial pruning.
        
        Value – The maximum ratio of spatial coverage.
        
        TableArn – The Amazon Resource Name (ARN) of the table with sub-optimal spatial pruning.
        
        PartitionKey – The partition key used for partitioning, which can be a default measure_name or a CDPK.
        
        Value (float) –
        
        The maximum ratio of spatial coverage.
        
        TableArn (string) –
        
        The Amazon Resource Name (ARN) of the table with the most sub-optimal spatial pruning.
        
        PartitionKey (list) –
        
        The partition key used for partitioning, which can be a default measure_name or a customer defined partition key.
        
        (string) –
        
        QueryTemporalRange (dict) –
        
        Provides insights into the temporal range of the query, including the table with the largest (max) time range. Following are some of the potential options for optimizing time-based pruning:
        
        Add missing time-predicates.
        
        Remove functions around the time predicates.
        
        Add time predicates to all the sub-queries.
        
        Max (dict) –
        
        Encapsulates the following properties that provide insights into the most sub-optimal performing table on the temporal axis:
        
        Value – The maximum duration in nanoseconds between the start and end of the query.
        
        TableArn – The Amazon Resource Name (ARN) of the table which is queried with the largest time range.
        
        Value (integer) –
        
        The maximum duration in nanoseconds between the start and end of the query.
        
        TableArn (string) –
        
        The Amazon Resource Name (ARN) of the table which is queried with the largest time range.
        
        QueryTableCount (integer) –
        
        Indicates the number of tables in the query.
        
        OutputRows (integer) –
        
        Indicates the total number of rows returned as part of the query result set. You can use this data to validate if the number of rows in the result set have changed as part of the query tuning exercise.
        
        OutputBytes (integer) –
        
        Indicates the size of query result set in bytes. You can use this data to validate if the result set has changed as part of the query tuning exercise.
      - ErrorReportLocation (dict) –
        
        S3 location for error report.
        
        S3ReportLocation (dict) –
        
        The S3 location where error reports are written.

        S3 bucket name.
        
        ObjectKey (string) –
        
        S3 key.
      - FailureReason (string) –
        
        Error message for the scheduled query in case of failure. You might have to look at the error report to get more detailed error reasons.
