After this session you will be able to say Garbage Collection tuning isn’t rocket science, it’s common sense. You will learn Key Performance Indicators (KPIs), useful tools, best practices and algorithms to tune your system’s garbage collection. Besides tuning, you will also learn how to use garbage collection metrics to troubleshoot and even forecast memory problems.

It was easy to understand the GC simple, clean explanation, it should have been more time to cover the whole slide and explanation.

The ArrayList should not be nullified if inside a thread stack (it becomes unreachable once it goes out of scope), only if it is a member variable...

How do we turn on gclog with K8S which doesn't suggest using persistent volume at all.

@maheshdevda6928 2 года назад

The same way you would without Kubernetes. I think you can also pass JVM arguments in the deployment file. For example, containers: - image: tomcat:9-jre8 name: tomcat env: - name: JAVA_OPTS value: "-Xlog:gc=debug:file=/tmp/gc.log:time,uptime,level,tags:filecount=5,filesize=100m"

35:08 JVM has the heap with it. JVM is running stuffs with it. I didnot get the part of pulling out JVM from the server (Running System.gc() in the server. How it is working).

@ramlakshmanan5313 Год назад

Hello Vishnu! I meant that JVM can be pulled out from the Load Balancer pool. System.gc() can be triggered and then JVM can put back in to the pool. So that GC pause time will not impact customer transactions.

I have a doubt, at 43:12 in that example, ArrayList will be increased by half of its original size right? for example, if the initial size of the List is 10, then it would be 15, when we try to insert 11th element.

@ramlakshmanan5313 3 года назад

Hello Laxman! Greetings. ArrayList size double when it's capacity limit is reached. Say if current capacity is 10 and when you try to add 11th element, ArrayList will double up. From it's current size of 10, it will become 20. Thanks.

@laxman20101 3 года назад

@@ramlakshmanan5313 greetings!!! I just reverified. The grow method increases the list by half of its size. So it would be 15 when 11th element added. (This is for arraylist).

@ramlakshmanan5313 3 года назад

@@laxman20101 Oh good to know. What version of Java are you using? How did you verify it? Thanks.

@laxman20101 3 года назад

I have verified it using Java 8, in arraylist add method , it ensures the capacity before adding any new element. If the size exceeds it has a private method grow, which does the job of increasing the size. newCapacity = oldCapacity + (oldCapacity >> 1) So it would be "newCapacity = 10 + 5"
