2018-11-13 TC Meeting notes

• https://forum.openlmis.org/t/improving-the-developer-experience/850
• What's next?

• Quick update that I'm looking at Change Data Capture (with Debezium) as an approach to data pumps:
  • Still very much in exploration - no decision or course change yet.  Though hope to get a sense for 3.6.
  • Streams changes from database, avoiding multiple writes (one to database, another as a published event)
  • CDC results in events in Kafka that look like the database, with schemas perhaps this is okay, however the event itself is often not the same higher-level semantic event we might think of (think of an Orderable vs. an Orderable with a Program Orderable).
    • One potential solution is to have a stream processor, perhaps even the service, which is responsible for making more semantic events for downstream clients.
    • Begs the question what, if anything, we'd use Nifi for.
