Fields

Modifier and Type	Field	Description
static int	DEFAULT_CENTROIDS_COUNT_LIMIT	Default centroids count limit, default to 100, meaning histogram with more then 100 centroids will throw TooManyCentroidException.
static int	DEFAULT_HISTOGRAM_ACCURACY	Default histogram accuracy, used when constructing new T-Digest for compression, and also controls the threshold for compression as well.
static double	DEFAULT_HISTOGRAM_COMPRESS_LIMIT_RATIO	Compress histogram limit when the count of centroid is larger then this ratio * accuracy.

Field Detail

DEFAULT_HISTOGRAM_COMPRESS_LIMIT_RATIO

public static final double DEFAULT_HISTOGRAM_COMPRESS_LIMIT_RATIO

Compress histogram limit when the count of centroid is larger then this ratio * accuracy. Default to 2, meaning when the count of centroids is larger then twice of histogram accuracy, perform the compression.
