QueryExecutionStatistics class
The amount of data scanned during the query execution and the amount of time that it took to execute, and the type of statement that was run.
Constructors

Properties
- dataManifestLocation → String?
-
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.
final
- dataScannedInBytes → int?
-
The number of bytes in the data that was queried.
final
- engineExecutionTimeInMillis → int?
-
The number of milliseconds that the query took to execute.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- queryPlanningTimeInMillis → int?
-
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.
final
- queryQueueTimeInMillis → int?
-
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.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- serviceProcessingTimeInMillis → int?
-
The number of milliseconds that Athena took to finalize and publish the
query results after the query engine finished running the query.
final
- totalExecutionTimeInMillis → int?
-
The number of milliseconds that Athena took to run the query.
final
