Quick study sessions to strengthen memory and retain key concepts.
Why is Flux useful for processing large datasets?
Flux processes data element-by-element, preventing memory overload. By processing items one at a time, Flux avoids loading a…
View Card →How does Flux represent a stream of data in Project Reactor?
Flux represents a stream of 0 to n items, including infinite streams. Flux is used when you need…
View Card →Why might WebFlux with Virtual Threads be advantageous over traditional models?
Virtual Threads can improve concurrency without blocking. Using WebFlux with Virtual Threads allows for high concurrency by reducing…
View Card →How would you explain the Publisher interface in the Reactive Streams Specification in an interview?
The Publisher interface defines a source of data in streams. In the Reactive Streams Specification, the Publisher is…
View Card →How does the map operator differ from flatMap in a Flux?
map transforms elements individually, flatMap handles them as streams. The map operator applies a transformation function to each…
View Card →What happens if you block the Event Loop in a WebFlux application?
Blocking the Event Loop can cause performance issues. In WebFlux applications, which are non-blocking by design, blocking the…
View Card →Why use Flux for infinite live websocket feeds?
Flux can manage continuous streams of data. Flux is ideal for handling infinite streams because it can emit…
View Card →How does the flatMap operator function in a Flux?
flatMap transforms each element into a Flux and flattens the results. The flatMap operator is used to asynchronously…
View Card →What differentiates Mono from Flux in Project Reactor?
Mono handles 0 or 1 item, Flux handles 0 to many items. Mono and Flux are both part…
View Card →Why does backpressure in a Flux matter in this design?
Backpressure controls the rate of data flow in a Flux. Backpressure is a mechanism to handle situations where…
