One of the basic requirement to enable big-data analytics is a rational and effective approach to data ingestion. In long running projects the need arises to evolve the domain model and this potentially affects data quality. As a consequence, the concept of versioning is crucial to keep data centric systems consistent: the importance of service dynamicity and good modularity support in a sound data ingestion workflow implementation cannot be easily overestimated.

This talk demonstrates how to combine OSGi declarative services and OSGi robust versioning support to enable complex data ingestion use cases such as serialization upcasting, domain and data models segregation and events versioning. Both Akka and Cassandra are offered as OSGi services to materialize big-data processing workflows with no pain.
