Task: Fix All 6 Disabled Unit Tests — PRGCRM-7126 I have implemented Jira ticket PRGCRM-7126: Restrict Journey Configuration Mode , and the changes have already been merged into the main branch. As part of this implementation, I added a new unit test class: SendServiceConfigurationControllerTest.java Currently, six test methods in this class are annotated with: @Disabled("Issue, needs to be fixed") Your task is to properly fix and enable all six test cases without changing the existing production implementation or business behavior. 1. Analyze the existing implementation first Read and understand the following files: SendServiceConfigurationControllerTest.java SendServiceConfigurationController.java EventDefinitionConfigurationDbService.java EventDefinitionConfigModeEnum.java EmailConfigRequest.java Also inspect any other directly related classes if necessary. Understand how journey configuration modes are validated and how the controller handles exceptions. Pay particular at...

Kafka Batching

Image
1. हिंदी में समझिए — Kafka Streams migration में अलग से batching क्यों implement करनी पड़ी? भाई, आपका reason technically सही है। लेकिन manager को explain करते समय एक important distinction रखना है: आपने batching कोई नई business functionality जोड़ने के लिए implement नहीं की थी। आपने existing @KafkaListener का batch-processing behavior Kafka Streams migration के बाद भी बनाए रखने के लिए implement की थी। पहले @KafkaListener में क्या हो रहा था? Spring Kafka में batching का support पहले से available था। हमारे existing implementation में: Kafka consumer एक poll में multiple records fetch कर सकता था। Spring Kafka का batch listener उन records को List<ConsumerRecord<String, String>> के रूप में method को देता था। max.poll.records और batch listener configuration से यह behavior control होता था। हमारा existing Data Service consumer पूरी list को एक साथ process करता था। इसलिए हमें manually records collect करने की जरूरत नहीं थी। Kafka Streams में migrate करने के बाद क्या बदला? Kafka Stre...

My Challanging Work

Image
  Challenging work i have done in my previous project ✅ 1️⃣ One-minute interview explanation (you can speak this) “We were reading millions of records from one system and inserting them into another database. Initially, we faced performance issues and OutOfMemoryError because the entire data was loaded into memory. To solve this, I implemented batch processing with multithreading. I processed records in chunks of 1000, performed transformation, inserted them into the database, cleared memory, and then processed the next batch. This made the system memory-efficient and scalable public void processLargeData(List<String> records) {         for (int i = 0; i < records.size(); i += BATCH_SIZE) {             int end = Math.min(i + BATCH_SIZE, records.size());             List<String> batch = records.subList(i, end);...

Thread Termination and Demon Thread

Image
 Thread Termination: Why : Because Thread are Consuming Resources : Like Memory, Kernel Recourses, cpu Cycle and cache memory When: 1. if thread finished its work, so we need to clean up the thread's resources 2. if thread misbehaving  3. By default application will not stope the thread as long as at least one thread is still running  Therad.intrrupt(): 1 if the thread is executing a method that throws an intrrupedException 2. if the thread's code is handling the interrupt signal explicitly  3.  If any one of the thread is in sleeping or waiting state (i.e. sleep() or wait() is invoked), calling the Thread.interrupt() method on the thread, breaks out the sleeping or waiting state throwing InterruptedException. If the thread is not in the sleeping or waiting state, calling the interrupt() method performs normal behavior and doesn't interrupt the thread but sets the interrupt flag to true   Daemon Thread: Daemon threads are thread that do not prevent the...
