Constructor Detail

DefaultingVolatileIntervalsService

public DefaultingVolatileIntervalsService()

Use the no op interval function with no customized functions.

DefaultingVolatileIntervalsService

public DefaultingVolatileIntervalsService(VolatileIntervalsFunction defaultIntervalsFunction)

Use a single default function for all physical tables.

Parameters:

defaultIntervalsFunction - The volatile intervals function to apply to all physical tables.

DefaultingVolatileIntervalsService

@Deprecated
public DefaultingVolatileIntervalsService(DefaultingDictionary<PhysicalTable,VolatileIntervalsFunction> intervalsFunctions)

Deprecated. Simply use maps and default values

Use the map of specific functions for physical tables.

Parameters:

intervalsFunctions - the map of specific functions for physical tables

DefaultingVolatileIntervalsService

public DefaultingVolatileIntervalsService(VolatileIntervalsFunction defaultIntervalsFunction,
                                          Map<PhysicalTable,VolatileIntervalsFunction> intervalsFunctions)

Use a default function with overrides for particular tables.

Parameters:

defaultIntervalsFunction - The volatile intervals function to apply to physical tables

intervalsFunctions - A map of functions to provide volatile intervals for physical tables

Method Detail

getVolatileIntervals

public SimplifiedIntervalList getVolatileIntervals(Granularity granularity,
                                                   List<org.joda.time.Interval> intervals,
                                                   PhysicalTable factSource)

Description copied from interface: VolatileIntervalsService

Retrieve a simplified sublist of the given intervals aligned to the specified time buckets and that are partially or fully volatile. Volatile intervals should not be cached (in the same way that partial intervals are not cached) but are returned to the user (which partial intervals are typically not). Volatile intervals will typically abut or overlap incomplete data because they are on the forward edge of ingestion.

Specified by:

getVolatileIntervals in interface VolatileIntervalsService

Parameters:

granularity - The granularity at which to check for volatility

intervals - The intervals that may contain a volatile sublist

factSource - The fact source table whose intervals are being retrieved

Returns:

A simplified interval list of volatile intervals
