case class AvgStringRDDMetricCalculator(sum: Double, cnt: Long, failCount: Long = 0, status: CalculatorStatus = CalculatorStatus.Success, failMsg: String = "OK") extends RDDMetricCalculator with Product with Serializable

Calculates average length of processed elements

sum

Current sum of lengths

cnt

Current count of elements

returns

result map with keys: "AVG_STRING"

Note

Null values are omitted: For values: "foo", "bar-buz", null Metric result would be: (3 + 7) / 2 = 5
