Class QueryExecutionStatistics

    • Method Detail

      • engineExecutionTimeInMillis

        public final Long engineExecutionTimeInMillis()

        The number of milliseconds that the query took to execute.

        Returns:
        The number of milliseconds that the query took to execute.
      • dataScannedInBytes

        public final Long dataScannedInBytes()

        The number of bytes in the data that was queried.

        Returns:
        The number of bytes in the data that was queried.
      • dataManifestLocation

        public final String dataManifestLocation()

        The location and file name of a data manifest file. The manifest file is saved to the Athena query results location in Amazon S3. The manifest file tracks files that the query wrote to Amazon S3. If the query fails, the manifest file also tracks files that the query intended to write. The manifest is useful for identifying orphaned files resulting from a failed query. For more information, see Working with Query Results, Output Files, and Query History in the Amazon Athena User Guide.

        Returns:
        The location and file name of a data manifest file. The manifest file is saved to the Athena query results location in Amazon S3. The manifest file tracks files that the query wrote to Amazon S3. If the query fails, the manifest file also tracks files that the query intended to write.

      • totalExecutionTimeInMillis

        public final Long totalExecutionTimeInMillis()

        The number of milliseconds that Athena took to run the query.

        Returns:
        The number of milliseconds that Athena took to run the query.
      • queryQueueTimeInMillis

        public final Long queryQueueTimeInMillis()

        The number of milliseconds that the query was in your query queue waiting for resources. Note that if transient errors occur, Athena might automatically add the query back to the queue.

        Returns:
        The number of milliseconds that the query was in your query queue waiting for resources. Note that if transient errors occur, Athena might automatically add the query back to the queue.
      • servicePreProcessingTimeInMillis

        public final Long servicePreProcessingTimeInMillis()

        The number of milliseconds that Athena took to preprocess the query before submitting the query to the query engine.

        Returns:
        The number of milliseconds that Athena took to preprocess the query before submitting the query to the query engine.
      • queryPlanningTimeInMillis

        public final Long queryPlanningTimeInMillis()

        The number of milliseconds that Athena took to plan the query processing flow. This includes the time spent retrieving table partitions from the data source. Note that because the query engine performs the query planning, query planning time is a subset of engine processing time.

        Returns:
        The number of milliseconds that Athena took to plan the query processing flow. This includes the time spent retrieving table partitions from the data source. Note that because the query engine performs the query planning, query planning time is a subset of engine processing time.
      • serviceProcessingTimeInMillis

        public final Long serviceProcessingTimeInMillis()

        The number of milliseconds that Athena took to finalize and publish the query results after the query engine finished running the query.

        Returns:
        The number of milliseconds that Athena took to finalize and publish the query results after the query engine finished running the query.
      • resultReuseInformation

        public final ResultReuseInformation resultReuseInformation()

        Contains information about whether previous query results were reused for the query.

        Returns:
        Contains information about whether previous query results were reused for the query.
      • hashCode

        public final int hashCode()
        Overrides:
        hashCode in class Object
      • equals

        public final boolean equals​(Object obj)
        Overrides:
        equals in class Object
      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
        toString in class Object
      • getValueForField

        public final <T> Optional<T> getValueForField​(String fieldName,
                                                      Class<T> clazz)
