ReactivePersistence

Reactive Persistence (R2DBC)

Idea

UI with:

• status bar (threads, requests)
• some useful operations

Application Logic

                 |= External WebService
UI = WebService =|
                 |= Database

Open questions

• WebFlux Netty does not support HTTP/2, only Tomcat
• Do we need TLS for HTTP/2
• May we somehow interact with the audience?

The Flow of Examples

• Blocking Web App (Spring WebMVC)
• Rx Web App (Spring WebFlux)
• Rx Web App with Blocking External Request (Http 11 Client)
• Rx Web App with Rx External Request (WebClient)
• Rx Web App with Rx External Request and Reactive DB
  • Cassandra
  • MongoDB
  • Couchbase
• Rx Web App with Rx External Request and Postgres
  • JDBC wrapped in Thread Pool
  • R2DBC
