| /** |
| * Library of arithmetic operators. |
| * <br> |
| * Most of the arithmetic operators come in three types based on their schema. |
| * The operators whose names ends with "Map" (eg SumMap, MaxMap, MinMap) take in Map on input ports and emit HashMap. These operators use |
| * round robin partitioning and would merge as per their functionality. |
| * <br> |
| * The operators whose names ends with "KeyVal" (eg SumKeyVal, MaxKeyVal, MinKeyVal) take in KeyValPair and emit KeyValPair. These operators use |
| * sticky key partitioning and would merge using default pass through merge operator. |
| * <br> |
| * The operators whose names are just their function name (eg Sum, Min, Max) operate on same objects and emit a final result. These operators have no keys. |
| * They partition in roundrobin and would merge as per their functionality. |
| * <br> |
| * Average, Quotient operators are non-partitionable. |
