Key-value pairs data processing apparatus and method

A data processing apparatus, comprising:

• a storage unit, being stored with a first key-value set and a second key-value set, the first key-value set comprising a plurality of first key-value pairs, each of the first key-value pairs comprising a first key and a first value, the second key-value set comprising a plurality of second key-value pairs, and each of the second key-value pairs comprising a second key and a second value;
• an interface, being configured to receive an instruction regarding a set operation and a function;
• and
• a processor, being electrically connected to the storage unit and the interface and configured to generate a plurality of third keys by applying the set operation to the first keys and the second keys, wherein the third key is equivalent to one of the first keys and the second keys,
• where in the processor is further configured to generate a third value for each of the third keys by applying the function to at least one of the first values and the second values corresponding to the third key,
• wherein each of the third keys and the corresponding third value form a third key-value pair and the third key-value pairs form a third key-value set.

A data processing method for use in a computer system, the computer system being stored with a first key-value set comprising a plurality of first key-value pairs, each of the first key-value pairs comprising a first key and a first value, the data processing method comprising the following steps of:

• (a) receiving an instruction regarding a set operation, a function, and a factor;
• (b) generating a plurality of second keys by applying the set operation to the first keys so that each of the second keys comprises at least one of the first keys, wherein a size of each of the second keys is equivalent to the factor;
• and
• (c) generating a second value for each of the second keys by applying the function to at least one datum corresponding to the at least one first key comprised in the second key,
• wherein each second key and the corresponding second value form a second key-value pair and the second key-value pairs form a second key-value set.
