Method Detail

getTaskType

public TaskType getTaskType()

Specified by:

getTaskType in interface Task

getTarget

public String getTarget()

Description copied from interface: Task

This is a key or identifier of the time series that is associated with the task. Consider aggregating metrics or events as an example. Let's say there is a task for computing a 5 minute rollup from raw data. This property should be the key or identifier of the 5 minute rollup time series.

Specified by:

getTarget in interface Task

getSources

public Set<String> getSources()

Description copied from interface: Task

The keys or identifiers of the time series associated with the source data being operated on. There can be one or more sources. Consider aggregating metrics or events as an example. There is a task for computing a 5 minute rollup from raw data. This property identifies the time series of the raw data to be aggregated.

Specified by:

getSources in interface Task

getInterval

public org.joda.time.Duration getInterval()

Description copied from interface: Task

The frequency of the task execution, e.g., five minutes.

Specified by:

getInterval in interface Task

getWindow

public org.joda.time.Duration getWindow()

Description copied from interface: Task

Specifies the amount of data to be included. For an aggregation task that runs every 5 minutes with a window of 15 minutes, the task should query for data from the past 15 minutes using timeSlice as the end time.

Specified by:

getWindow in interface Task

getTimeSlice

public org.joda.time.DateTime getTimeSlice()

Description copied from interface: Task

The end time of the time slice for which the task is scheduled. If a task has an interval of an hour, then the time slice would be 9:00 - 10:00, 10:00 - 11:00, etc. The task is guaranteed to run no earlier than this time.

Specified by:

getTimeSlice in interface Task
