KanDDDinsky 2017 - The Dark Side of Event Sourcing: Managing Data Conversion

Evolving software systems often includes data schema changes, and those cause the need for data conversion. This is no different in event sourced systems.

We will look at the possibilities and the trade-offs for designing and implementing upgrades for event sourced systems.
