  • buns that Cassandra gives
  • restrictions on use
  • examples of how you can and how you don’t need to build a data structure

“Reactive programming and reactive driver for R2DBC relational databases”

Recall what reactive programming is and what it is used for, where it can come in handy. Let’s talk about whether we use it in production.

We will talk about Mono, Flux, the specifications of reactive streams, the specifications of R2DBC, consider what are the low-level implementations of divers, as well as client implementations (pure reactor, spring data).

Is everything already “implemented” and ready to go to the prod. And finally, let’s talk about the overall performance of Webflux.
