module DDSketch
  # The default implementation of DDSketch, with optimized memory usage at
  # the cost of lower ingestion speed, using an unlimited number of bins. The
  # number of bins will not exceed a reasonable number unless the data is
  # distributed with tails heavier than any subexponential.

    # @param [Float] relative_accuracy The guaranteed relative accuracy for sketch
