Simulate two parallel WebClient calls using Mono.zip(). Call getUser() which returns Mono.just("Alice") and getRole() which returns Mono.just("Admin"). Zip them together and print "Alice is Admin".

Mono.zip() executes both calls concurrently and combines their results.

Parallel Calls with Zip

medium⏱ 15 minkotlinreactorchallengewebclient

Simulate two parallel WebClient calls using Mono.zip(). Call getUser() which returns Mono.just("Alice") and getRole() which returns Mono.just("Admin"). Zip them together and print "Alice is Admin".

Mono.zip() executes both calls concurrently and combines their results.

Why this works

Mono.zip() subscribes to multiple Monos concurrently and combines their results when all complete. This is ideal for making independent API calls in parallel, significantly reducing response time.

Expected output

Alice is Admin
