Module timely::dataflow::channels::pact [−][src]
Parallelization contracts, describing how data must be exchanged between operators. Parallelization contracts, describing requirements for data movement along dataflow edges.
Pacts describe how data should be exchanged between workers, and implement a method which
creates a pair of Push
and Pull
implementors from an A: AsWorker
. These two endpoints
respectively distribute and collect data among workers according to the pact.
The only requirement of a pact is that it not alter the number of D
records at each time T
.
The progress tracking logic assumes that this number is independent of the pact used.
