If by 'input/output' sources, you mean computations that will pull or push from an external system such as kafka/cassandra, there isn't any documentation currently. However we have written connectors to Kafka and Kinesis. You can check out the Scala Kafka Source here [1]. Internally we are working on a high performance Kafka Source in C++ (based on librdkafka). At the moment this source can push records downstream at a rate of > 350K QPS.

I meant connectors. Thanks for the pointer.
