🎯 Key Takeaways for quick navigation:

00:29 Phân *vùng nghĩa là chia tập dữ liệu thành các phần và gán cho các luồng xử lý khác nhau.*
00:58 Bạn *có thể tăng hiệu suất bằng cách sử dụng nhiều luồng hơn, mỗi luồng xử lý ít dữ liệu hơn.*
06:56 PartitionHandler *định nghĩa số lượng luồng, kích thước mỗi phân vùng và bước thực thi các phân vùng đó.*
11:49 Bước *master gọi đến PartitionHandler để phân chia nhiệm vụ, các bước slave thực thi các phần được phân chia.*
20:10 Có *thể cấu hình số lượng luồng và kích thước phân vùng dựa trên yêu cầu để tối ưu hiệu suất.*

Using SynchronizedItemStreamReader would be ideal when reading from same file using multiple threads.

HI BRO I WATCH YOUR VIDEOS...ONE SUGGESTION REGARDING VIDEOS MAKE ONE VIDEO EVERY YEAR JUST TO INFORM YOUR SUBSCRIBERS SO THAT THEY HAVE BASIC UNDERSTANDING WHICH TECHNOLOGY IS CURRENTLY IN TRENDS AND WHAT ARE THE TECHNOLOGIES THAT ARE CURRENTLY USED WITH JAVA IN INDUSTRY AND TECHNOLOGY AND ITS SCOPE FROM CAREER PERSPECTIVE BECAUSE THAT WOULD REALLY HELP US TO UNDERSTAND WHAT SHOULD WE LEARN.... THE ROAD MAP FOR LEARNING TECHNOLOGIES AND PLEASE MAKE VIDEOS REGARDING PROJECT DEVELOPMENT TIPS AND TRICKS AND MISTAKES THAT WE SHOULD AVOID WHILE DEVELOPING PROJECTS AND ONCE IN A WHILE DO QnA VIDEOS

How to stop a job once any of the partitioned step throws an exception, as currently other partitioned steps keep running till the end and after they complete, the job stop with unsuccessful return code.

[vanshikamalhotra]

please create video on design patterns also

[singhbangalore]

Hi There, one quick question - partitioning over single instance of server is fine, but how to deal when there are multiple instances of server where this batch application is running on.

e.g. there is a file with 1 million records and in my cloud environment there are 4 server instances where this batch application is running. how to develop the code in this cluster kind of environment for efficiently handling the record processsing using spring batch? - Thnx

[gdaimm]

Hi Java techie, can you please tell me how to read all data from multiple file locations.
Thank you

[rhimanshu]

Good tutorial!! What if any Step method has some parameters in it `public Step writer, readerDataInitialization). How to call this method from partitionHandler()

[jpnr]

will it work on multiple process? for example if i run the batch process on multiple pods.. if pod1 receives the request and execute the job. .will pod2 can automatically pickup the steps for execution?

[satyasai]

Sir colud u please upload splunk vedio. Monitoring purpose

[Rakesh]

This is all good, but i want to tell you that you should not take one file and split record counts while explaining Partitioning. You should have taken multiple files and pass file names from master to slave as reader param. And your Partitioning number could be based on supported core on machine.

[krishnakanthkolli]

[sugarod_]
