Sink Adapter
The Sink adapter is used as a temporary data destination for an output map card
which then discards the mapped data.
This capability is useful when a temporary destination is needed to accept output
data as part of the map execution without writing the output to a stationary
destination.
Using the Sink Adapter
The Sink adapter does not require any adapter commands for its operation. In
addition, the Sink adapter does not access a persistent source or destination,
therefore, a rollback and retry capability is not provided.
For example, use a Sink adapter instead of a file as the destination for temporary
output. The advantages of using the Sink adapter, in this case, include:
♦ faster map performance due to less file I/O
♦ reduced file resource conflicts when running multiple instances of the map
♦ reduced disk space usage
