Garbage Collection Algorithms in Java: Concurrent Updates with Optimistic Locking - Part III

We discuss how concurrent compaction using Compare and Swap (CAS) operations helps speed up garbage collection algorithms and reduce response latencies.
This is the last piece of the puzzle in the garbage collection series. Cheers!
Garbage collection is a way of automatic memory management provided by modern programming languages like Java, Go, Python and JavaScript.

keep them deep contents coming, gkcs 🎉🎉
many thanks!!!

[@debojitchakraborty6516]

Clear, concise and to the point. Can you please create a video suggesting which GC Algo would be beneficial for which kinda applications? May be on the basis of traffic, memory footprint etc.

[@gkcs]

There are four algorithms to choose from when setting the garbage collector in Java. They offer tradeoffs, and most applications find a suitable one among the four.
-- Mark and Sweep (High throughput + High Latency)
-- Concurrent Mark and Sweep (Lower throughput + Lower Latency)
-- G1GC (Fewer stop the world incidents)
-- Shenandoah or ZGC (Lower Throughput + Very low latency)

thank you so much, that helps 🙂😊@@gkcs

[@pranaykanjolia9077]

thanks for concise and to the point video. Can u share some links for having Concurrent mark and sweep algo in detail (step by step phases)

Good day greetings

How do you motivate yourself to create videos on such a least discussed topic on which you know you're going to get very low number of views? I see there are only 4 comments.
Really appreciate the efforts you're putting into creating such knowledgeable videos whereas other youtubers are busy making fool of janta.

[@gkcs]

I feel like my purpose is to share important information. The impact is partly measured by views. The quality of the views matter too.
Knowing that at least 10 people will find this video useful is enough motivation for me ✈️
