Examples of Costs

eu.stratosphere.compiler.costs.Costs
Simple class to represent the costs of an operation. The costs are currently tracking, network, I/O and CPU costs. Costs are composed of two parts of cost contributors:
1. Quantifiable costs. Those costs are used when estimates are available and track a quantifiable measure, such as the number of bytes for network or I/O
2. Heuristic costs. Those costs are used when no estimates are available. They can be used to track that an operator used a special operation which is heuristically considered more expensive than another operation.
The quantifiable costs may frequently be unknown, which is represented by a {@code -1} as a value for the unknowncomponents of the cost. In that case, all operations' costs are unknown and hence it is not decidable which operation to favor during pruning. In that case, the heuristic costs should contain a value to make sure that operators with different strategies are comparable, even in the absence of estimates. The heuristic costs are hence the system's mechanism of realizing pruning heuristics that favor some operations over others.
