PRGCRM-5120 — Generate Complete Kafka Streams Batching Implementation Documentation Act as a senior Java 21, Spring Boot, Apache Kafka Streams engineer and technical documentation specialist. I have implemented Kafka Streams batching changes for Jira PRGCRM-5120 . Current feature branch: PRGCRM-5120_DataService_Kafka Baseline branch: origin/main Primary objective Generate ONE comprehensive Markdown document explaining: What we implemented. Why the changes were required. What problems existed before the latest corrections. How the corrections solve those problems. How the current implementation works internally. What impact it has on Data Service. How the implementation addresses the PR review comments. What has been tested and what remains unverified. How I can explain these changes to my manager and Mathieu. The documentation must be based on the actual current source code, Git diffs, and tests, NOT merely on previous AI-generated summaries. STEP 1 — Inspect actual implementation Ve...

Kafka Batching

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);...
