ClassDescriptionThis a convenience class for interpreting summary data generated by implementations of
CountingSummarizerThis class counts arbitrary keys while defending against too many keys and keys that are too long.A function that converts key values to zero or more counter objects.Instances of this interface can be configured for Accumulo tables.When Accumulo calls methods in this interface, it will callSummarizer.Collector.accept(Key, Value)zero or more times and then callSummarizer.Collector.summarize(Summarizer.StatisticConsumer)once.A Combiner is used to merge statistics emitted fromSummarizer.Collector.summarize(Summarizer.StatisticConsumer)and from previous invocations of itself.This class encapsulates the configuration needed to instantiate aSummarizer.This class encapsulates summary statistics, information about how those statistics were generated, and information about files the statistics were obtained from.
