Spring batch introduction

-

  • An open source framework to create batch processing application which can deal with the high volume of data, capable to handle processing of billions of records in a day efficiently.
  • Lightweight framework – consume very less memory.
  • It’s not a scheduling framework
  • Provide out of the box APIs to read, process and write data. 
  • Efficient transaction management and error handling.

Why does the batch job needed?

  • Automate the complex processing (applying business logic on data/transforming data) of large volumes of data without any user interaction.

Spring Batch vs Spring Boot Batch -

  • ·Spring batch is a batch processing framework and spring boot help us to do rapid development by using starter-templates (convention over configuration).

What are the ideal use cases for the batch job?

  • Reads the high volume of records from the database/file system.
  •  Process the data e.g. Month-end / Weekend calculations
  • Write back processed data / generates reports

What are the different ways to achieve high-performance batch processing?

  • Parallel steps
  • Multithreaded steps
  • Partitioning

What are the advantages of spring batch?

·         Easy to configure, customize by leveraging the spring framework in all layers.
·         Easy to build and deploy.
·         Developers only needs to focus on business logic other things will be taken care by the framework, like records processed, how many records are remaining to process how to commit those records etc.

Right way to close HttpsURLConnetion using try with resources in java 8

-
HttpsURLConnection does not implement the AutoCloseable interface in Java 8 or later versions. Since HttpsURLConnection does not implement AutoCloseable, you cannot use it directly in a try-with-resources block. However, you can create a wrapper class that implements AutoCloseable and encapsulates the HttpsURLConnection object, and then use the wrapper class in a try-with-resources block. Here's an example of how to create a wrapper class for HttpsURLConnection that implements AutoCloseable: public class HttpsURLConnectionWrapper implements AutoCloseable { private final HttpsURLConnection connection; public HttpsURLConnectionWrapper(URL url) throws IOException { connection = (HttpsURLConnection) url.openConnection(); } public HttpsURLConnection getConnection() { return connection; } @Override public void close() throws IOException { connection.disconnect(); } } In this example, the HttpsURLConnectionWrapper c...

Spring Boot Batch - Parallel Processing (Running Multiple Jobs Concurrently)

If you are new to Spring batch please check the earlier post about S pring batch introduction In this post we will see Spring boot batch example, Spring boot batch parallel processing example Spring boot batch parallel processing allows multiple batch jobs to run in parallel to minimize the total elapsed batch processing time. This is not a problem as long as the jobs are not sharing the same files, db-tables, or index spaces. If they do, this service should be implemented using partitioned data. We will create the application having the following 2 jobs -  1st Job: Reads the P roduct information from the database and after processing will give the rating to the project. 2nd Job: Reads the Invoice the information the database and update back to the database.  We are not focusing on the business logic here but the processing of data using multiple jobs. Technical Details -  Java 8 Spring Boot 2.x Spring Batch 4.x MySql 5...

Git – Introduction There are many popular DVCS systems like Git, Mercurial, Bazaar which has grown maturely to implement distributed revision across their products. Git is widely used by the development teams across the world due to its simplicity, active open source the development team  and frequent releases/patches. Before moving forward with the git concepts, few of them terminologies which will be frequently used in this tutorial are defined below : Remote Repository : This refers to the specific project space on the central server where the project source code is stored and will be used by the team members for checkout or commit. Local Repository (.git directory): There is a local folder “.git” which is automatically created when the project or folder is git tracked. The “.git” folder is like a local database which will contain all information related to branches, commit history, user configurations, and metadata. Branches / Tags – Has the same definition as ...
