    public interface BloomCommands<K,​V>
    extends RedisCommands
    Allows executing commands from the bloom group. These commands require the Redis Bloom module to be installed in the Redis server.

    See the bloom command list for further information about these commands.

    • Method Detail

      • bfadd

        boolean bfadd​(K key,
                      V value)
        Execute the command BF.ADD. Summary: Adds the specified element to the specified Bloom filter. Group: bloom

        If the bloom filter does not exist, it creates a new one.

        Parameters:
        key - the key
        value - the value, must not be null
        Returns:
        true if the value did not exist in the filter, false otherwise.
      • bfexists

        boolean bfexists​(K key,
                         V value)
        Execute the command BF.EXISTS. Summary: Determines whether an item may exist in the Bloom Filter or not. Group: bloom
        Parameters:
        key - the key
        value - the value, must not be null
        Returns:
        true if the value may exist in the filter, false means it does not exist in the filter.
      • bfmadd

        List<Boolean> bfmadd​(K key,
                             V... values)
        Execute the command BF.MADD. Summary: Adds one or more items to the Bloom Filter and creates the filter if it does not exist yet. This command operates identically to BF.ADD except that it allows multiple inputs and returns multiple values. Group: bloom

        Parameters:
        key - the key
        values - the values, must not be null, must not contain null, must not be empty.
        Returns:
        a list of booleans. true if the corresponding value did not exist in the filter, false otherwise.
      • bfmexists

        List<Boolean> bfmexists​(K key,
                                V... values)
        Execute the command BF.MEXISTS. Summary: Determines if one or more items may exist in the filter or not. Group: bloom
        Parameters:
        key - the key
        values - the values, must not be null, must not contain null, must not be empty.
        Returns:
        a list of booleans. true if the corresponding value may exist in the filter, false does not exist in the filter.
      • bfreserve

        void bfreserve​(K key,
                       double errorRate,
                       long capacity)
        Execute the command BF.RESERVE. Summary: Creates an empty Bloom Filter with a single sub-filter for the initial capacity requested and with an upper bound error_rate. Group: bloom
        Parameters:
        key - the key
        errorRate - The desired probability for false positives. The rate is a decimal value between 0 and 1.
        capacity - The number of entries intended to be added to the filter.
      • bfreserve

        void bfreserve​(K key,
                       double errorRate,
                       long capacity,
                       BfReserveArgs args)
        Execute the command BF.RESERVE. Summary: Creates an empty Bloom Filter with a single sub-filter for the initial capacity requested and with an upper bound error_rate. Group: bloom
        Parameters:
        key - the key
        errorRate - The desired probability for false positives. The rate is a decimal value between 0 and 1.
        capacity - The number of entries intended to be added to the filter.
        args - the extra parameters
      • bfinsert

        List<Boolean> bfinsert​(K key,
                               BfInsertArgs args,
                               V... values)
        Execute the command BF.INSERT. Summary: BF.INSERT is a sugarcoated combination of BF.RESERVE and BF.ADD. It creates a new filter if the key does not exist using the relevant arguments. Next, all ITEMS are inserted. Group: bloom

        Parameters:
        key - the key
        args - the creation parameters
        values - the value to add, must not contain null, must not be null, must not be empty
        Returns:
        a list of booleans. true if the corresponding value may exist in the filter, false does not exist in the filter.
