Event Sourcing with CQRS.

  The way event sourcing works with CQRS is to have  part of the application that models updates as writes to an event log or Kafka topic . This is paired with an event handler that subscribes to the Kafka topic, transforms the event (as required) and writes the materialized view to a read store.

GraphQL microservices (GQLMS)

I'm curios of GraphQL !     -  GraphQL is an open-source data query and manipulation language for APIs, and a runtime for fulfilling queries with existing data. GraphQL was developed internally by Facebook in 2012 before being publicly released in 2015. It should be solving a problem in querying data !     -GraphQL lets you ask for what you want in a single query, saving bandwidth and reducing waterfall requests. It also enables clients to request their own unique data specifications. A case study ?!    -https://netflixtechblog.com/beyond-rest-1b76f7c20ef6 So, This is just another database technoloy ?  -  No. GraphQL is often confused with being a database technology. This is a misconception, GraphQL is a   query language   for APIs - not databases. In that sense it’s database agnostic and can be used with any kind of database or even no database at all.
