Designing data intensive applications : Chapter 8: The Trouble with Distributed Systems

Many programming language runtimes (such as the Java Virtual Machine) have
a garbage collector (GC) that occasionally needs to stop all running threads.
These “stop-the-world” GC pauses have sometimes been known to last for several
minutes [64]! Even so-called “concurrent” garbage collectors like the HotSpot
JVM’s CMS cannot fully run in parallel with the application code—even they
need to stop the world from time to time [65]. Although the pauses can often be
reduced by changing allocation patterns or tuning GC settings [66], we must
assume the worst if we want to offer robust guarantees.

For example, if your car’s onboard sensors detect that you are currently experiencing
a crash, you wouldn’t want the release of the airbag to be delayed due to an inoppor‐
tune GC pause in the airbag release system.

جالبه الان میفهمم چرا سی پلاس پلاس حرفه ای ترین انتخاب موجوده و کل دنیا رو گرفته قدیما فکر میکردم فقط بحث سرعته ولی الان میبینم مشکلات ساختاری دارند بقیه طوری که انتخابی بجز سی پلاس پلاس نمیمونه
