What potential issue should be considered when using AtomicInteger in a high-throughput application?
Multiple choiceHardchapter-15-curatedpremiumconcurrencyatomic-variables
Answer and explanation
Correct answer
C. False sharing due to cache line contention.
Why
In high-throughput applications, frequent updates to AtomicInteger can lead to false sharing, where multiple threads modify variables that reside on the same cache line, causing performance degradation due to cache line contention.
