Value Members

  1. object CodegenMetrics extends Source

    Metrics for code generation.

  2. object DoubleAccumulatorSource

    :: Experimental :: Metrics source specifically for DoubleAccumulators.

    :: Experimental :: Metrics source specifically for DoubleAccumulators. Accumulators are only valid on the driver side, so these metrics are reported only by the driver. Register DoubleAccumulators using: DoubleAccumulatorSource.register(sc, {"name" -> doubleAccumulator})

    Annotations
    @Experimental()
  3. object HiveCatalogMetrics extends Source

    Metrics for access to the hive external catalog.

  4. object LongAccumulatorSource

    :: Experimental :: Metrics source specifically for LongAccumulators.

    :: Experimental :: Metrics source specifically for LongAccumulators. Accumulators are only valid on the driver side, so these metrics are reported only by the driver. Register LongAccumulators using: LongAccumulatorSource.register(sc, {"name" -> longAccumulator})
