Key Insights from My Agile Experience

For Agile to be truly successful, a cohesive and stable team is essential. Sticking with the same team over time builds consistency, trust, and velocity.
Here’s how I like to define Agile in simple terms using an analogy:

Capturing JVM heap allocation and comparing it between two executions of a Java application can be super insightful when you're analyzing memory usage, leaks, or performance. Here’s a practical way to do it:

🚀 Step-by-Step Guide

✅ 1. Enable JVM Heap Monitoring

Use the following Java options when running your app to capture memory usage:

db.collectionA.insertMany([
    { "_id": 1, "field1A": "A", "field2A": 100 },
    { "_id": 2, "field1A": "B", "field2A": 200 }

]);

db.collectionB.insertMany([
 { "_id": 1, "field1B": "A", "field2B": 100 },
