Method Details
-
stageId
The identifier for a stage.
- Returns:
- The identifier for a stage.
-
state
State of the stage after query execution.
- Returns:
- State of the stage after query execution.
-
outputBytes
The number of bytes output from the stage after execution.
- Returns:
- The number of bytes output from the stage after execution.
-
outputRows
The number of rows output from the stage after execution.
- Returns:
- The number of rows output from the stage after execution.
-
inputBytes
The number of bytes input into the stage for execution.
- Returns:
- The number of bytes input into the stage for execution.
-
inputRows
The number of rows input into the stage for execution.
- Returns:
- The number of rows input into the stage for execution.
-
executionTime
Time taken to execute this stage.
- Returns:
- Time taken to execute this stage.
-
queryStagePlan
Stage plan information such as name, identifier, sub plans, and source stages.
- Returns:
- Stage plan information such as name, identifier, sub plans, and source stages.
-
hasSubStages
public final boolean hasSubStages()For responses, this returns true if the service returned a value for the SubStages property. This DOES NOT check that the value is non-empty (for which, you should check theisEmpty()method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified. -
subStages
List of sub query stages that form this stage execution plan.
Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the
hasSubStages()method.- Returns:
- List of sub query stages that form this stage execution plan.
