I've had a few conversations with different people recently on the subject of microservices and (distributed) transactions. One of my biggest worries about microservices in general is that we end up repeating the same conversations and disagreements that we had with SOA, REST and other related technologies. And one of the longest running debates we had during those specific waves was around transactions and their applicability, or not. I continue to believe that transactions are useful for some SOA-based services, though that doesn't mean they have to be atomic transactions. Therefore, I feel that they also have a role to play for microservices and took the opportunity to write down some of my thoughts on the topic.
