  • Method Details

    • hotKeyPercentage

      public double hotKeyPercentage()
      Get hot key percentage 获取热点键百分比
      Returns:
      hot key percentage | 热点键百分比

    • coldKeyPercentage

      public double coldKeyPercentage()
      Get cold key percentage 获取冷数据键百分比
      Returns:
      cold key percentage | 冷数据键百分比

    • isSkewed

      public boolean isSkewed()
      Check if access pattern is skewed (top 20% keys have 80% access) 检查访问模式是否倾斜（前 20% 的键占 80% 的访问）
      Returns:
      true if skewed | 如果倾斜返回 true

    • toMap

      public Map<String,Object> toMap()
      Convert to map for JSON serialization 转换为 Map 用于 JSON 序列化
      Returns:
      map representation | Map 表示

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.
