How does Scala optimize JVM garbage collection in high-throughput systems?

Scala relies on JVM GC tuning and reduces allocations via immutability and structural sharing.

Scala applications benefit from reduced object churn due to immutable structures. JVM GC tuning (G1GC, ZGC) helps manage large heaps. Functional pipelines are optimized to reduce temporary allocations, improving throughput in high-load systems.
