    • cmsIncrBy

      public long cmsIncrBy(K key, V value, long increment)
      Description copied from interface: CountMinCommands
      Execute the command CMS.INCRBY. Summary: Increases the count of item by increment. Multiple items can be increased with one call. Group: count-min

      Specified by:
      cmsIncrBy in interface CountMinCommands<K,V>
      Parameters:
      key - the name of the sketch, must not be null
      value - the value, must not be null
      increment - the increment
      Returns:
      the updated min-count for the added value

    • cmsIncrBy

      public Map<V,Long> cmsIncrBy(K key, Map<V,Long> couples)
      Description copied from interface: CountMinCommands
      Execute the command CMS.INCRBY. Summary: Increases the count of item by increment. Multiple items can be increased with one call. Group: count-min

      Specified by:
      cmsIncrBy in interface CountMinCommands<K,V>
      Parameters:
      key - the name of the sketch, must not be null
      couples - the set of value/increment pair, must not be null, must not be empty
      Returns:
      a map containing the updated min-count for each added value

    • cmsInitByDim

      public void cmsInitByDim(K key, long width, long depth)
      Description copied from interface: CountMinCommands
      Execute the command CMS.INITBYDIM. Summary: Initializes a Count-Min Sketch to dimensions specified by user. Group: count-min

      Specified by:
      cmsInitByDim in interface CountMinCommands<K,V>
      Parameters:
      key - the name of the sketch, must not be null
      width - the number of counters in each array. Reduces the error size.
      depth - the number of counter-arrays. Reduces the probability for an error of a certain size (percentage of total count).

    • cmsInitByProb

      public void cmsInitByProb(K key, double error, double probability)
      Description copied from interface: CountMinCommands
      Execute the command CMS.INITBYPROB. Summary: Initializes a Count-Min Sketch to accommodate requested tolerances. Group: count-min

      Specified by:
      cmsInitByProb in interface CountMinCommands<K,V>
      Parameters:
      key - the name of the sketch, must not be null
      error - estimate size of error. The error is a percent of total counted items (in decimal). This effects the width of the sketch.
      probability - the desired probability for inflated count. This should be a decimal value between 0 and 1.

    • cmsQuery

      public long cmsQuery(K key, V item)
      Description copied from interface: CountMinCommands
      Execute the command CMS.QUERY. Summary: Returns the count for one or more items in a sketch. Group: count-min

      Specified by:
      cmsQuery in interface CountMinCommands<K,V>
      Parameters:
      key - the name of the sketch, must not be null
      item - the item to check, must not be null
      Returns:
      the count for the given item

    • cmsQuery

      public List<Long> cmsQuery(K key, V... items)
      Description copied from interface: CountMinCommands
      Execute the command CMS.QUERY. Summary: Returns the count for one or more items in a sketch. Group: count-min

      Specified by:
      cmsQuery in interface CountMinCommands<K,V>
      Parameters:
      key - the name of the sketch, must not be null
      items - the items to check, must not be null, empty or contain null
      Returns:
      a list containing the count for the corresponding item

    • cmsMerge

      public void cmsMerge(K dest, List<K> src, List<Integer> weight)
      Description copied from interface: CountMinCommands
      Execute the command CMS.MERGE. Summary: Merges several sketches into one sketch. All sketches must have identical width and depth. Weights can be used to multiply certain sketches. Default weight is 1. Group: count-min

      Specified by:
      cmsMerge in interface CountMinCommands<K,V>
      Parameters:
      dest - The name of destination sketch. Must be initialized, must not be null
      src - The names of source sketches to be merged. Must not be null, must not contain null, must not be empty.
      weight - The multiple of each sketch. Default =1, can be empty, can be null
