  • No heavy ORM required, because customer data is read only in the Contract App
  • Read model is recreated every night to reflect latest changes
  • Mapping of legacy structure is done when building the read model
  • New features based on so far unused data can be added without new import

Projections for Speed

A B2B portal also needs customer data and Contract App has a http API, but...

... requires other structure of the data and filtering is based on other properties

... http API would have to handle lot of additional traffic

New Consumer

Dedicated Projection

Same customer event stream projected into a document store

Accessed by a microservice

Can be scaled independently of Contract App

?
