Data can be produced to Venice in a nearline fashion, from stream processors. The best supported stream processor is Apache Samza though we intend to add first-class support for other stream processors in the future. The difference between using a stream processor library and the Online Producer library is that a stream processor has well-defined semantics around when to ensure that produced data is flushed and a built-in mechanism to checkpoint its progress relative to its consumption progress in upstream data sources, whereas the online producer library is a lower-level building block which leaves these reliability details up to the user.
For Apache Samza, the integration point is done at the level of the VeniceSystemProducer and VeniceSystemFactory.
More details to come.
