Notes:

1. Service for each table
2. Local/own/isolated database for each service
3. Cache join query information locally on respective service's DBs on each write to avoid cascaded service calls (aka joins in monolithic/shared DB)
4. Alternative to ACID transactions is to perform multi-step operations using a state machine which can be rollbacked
5. Dealing with events
   5.1 At most once delivery - When you don't care about such events, like logging stuff using UDP
