> A primary objective of the Gelly examples {{Runner}} is to make adding new inputs and algorithms as simple and powerful as possible. A recent feature made it possible to translate the key ID of generated graphs to alternative numeric or string representations. For floating point and {{LongValue}} it is desirable to translate the key ID of the algorithm results.
> Currently a {{Runner}} job consists of an input, an algorithm, and an output. A {{Transform}} will translate the input {{Graph}} and the algorithm output {{DataSet}}. The {{Input}} and algorithm {{Driver}} will return an ordered list of {{Transform}} which will be executed in that order (processed in reverse order for algorithm output) . The {{Transform}} can be configured as are inputs and drivers.
> Example transforms:
> - the aforementioned translation of key ID types
> - surrogate types (String -> Long or Int) for user data
> - FLINK-4481 Maximum results for pairwise algorithms
> - FLINK-3625 Graph algorithms to permute graph labels and edges
