Anyone willing to know something specific about Debezium or Camel? In any case @wyclif and I will try to answer those questions.
Just to give a very quick update (see also this other thread from here), @wyclif is still spiking on figuring out whether we can find an architecture that uses Debezium (rather than custom DB triggers + a sync records table in the OpenMRS database) and that will help us support two-way sync.
