Arranges a stream of (Key, Val)
updates by Key
into a trace of type Tr
. Partitions
the data according to pact
.
This operator arranges a stream of values into a shared trace, whose contents it maintains. This trace is current for all times marked completed in the output stream, and probing this stream is the correct way to determine that times in the shared trace are committed.
