QueryExecutionStatistics

public struct QueryExecutionStatistics : AWSShape

Undocumented

  • Declaration

    Swift

    public static var _members: [AWSShapeMember]

  • 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.

    Declaration

    Swift

    public let dataManifestLocation: String?

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

    Declaration

    Swift

    public let dataScannedInBytes: Int64?

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

    Declaration

    Swift

    public let engineExecutionTimeInMillis: Int64?

  • 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.

    Declaration

    Swift

    public let queryPlanningTimeInMillis: Int64?

  • 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.

    Declaration

    Swift

    public let queryQueueTimeInMillis: Int64?

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

    Declaration

    Swift

    public let serviceProcessingTimeInMillis: Int64?

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

    Declaration

    Swift

    public let totalExecutionTimeInMillis: Int64?

  • Undocumented

    Declaration

    Swift

    public init(dataManifestLocation: String? = nil, dataScannedInBytes: Int64? = nil, engineExecutionTimeInMillis: Int64? = nil, queryPlanningTimeInMillis: Int64? = nil, queryQueueTimeInMillis: Int64? = nil, serviceProcessingTimeInMillis: Int64? = nil, totalExecutionTimeInMillis: Int64? = nil)
