I for some months now have tried to build a small test-case for a invoice app. I wish to have a good syn strategy and the use of ES sound good. However, I have find how replicate the functionality of a normal app with this: For example, what to do for avoid duplicates and in general pre-saving validations. Also, I need to anyway to use RDBMS tables for hold current-data and RDBMS have not a good history for stream back results.
