From Java Code → Bytecode → Constant Pool Hashes Code Example 🎯 Let’s take the simplest code: Java Code public class Demo { public static void main(String[] args) { Demo d = new Demo();...

Length-prefixed strings are one of the key reasons why Protocol Buffers (ProtoBuf) are smaller and faster than JSON or XML. In JSON or XML, strings are wrapped in quotes and require closing tags or...

The most important point about gRPC. Both Server and Client MUST have the proto file — or at least the generated classes from the proto file. Why is this necessary? Because gRPC doesn’t send...

You’re absolutely right to think that if keys are small and values are long, Protobuf’s advantage becomes less obvious — but it still helps in most cases. Let’s break it down 🔍: Scenario Imagine...

Unlike JSON, Protocol Buffers (Protobuf) use a compact binary format that removes redundant information. Here’s how data is structured and stored efficiently. 1️⃣ Protobuf Message Structure Let’s take a JSON-like structure: In Protobuf, we...

This example shows how to define, compile, serialize, and deserialize a Protocol Buffers (Protobuf) message in Java. 📌 Step 1: Define the Protobuf Schema Create a file named person.proto: Explanation: 📌 Step 2: Compile...

In GraalVM Native Image mode, the compiler removes unused code to reduce binary size. This means if a class, method, or field is:❌ Not directly used anywhere in the code AND❌ Not explicitly registered...

1. How Reflection Works in Traditional JVMs In a traditional JVM, reflection allows the application to:✅ Discover and inspect classes, methods, and fields at runtime✅ Dynamically instantiate objects and invoke methods✅ Access private members...

GraalVM’s Ahead-of-Time (AOT) compilation is one of its most revolutionary features. It allows Java applications to be compiled into a standalone native executable that does not require the JVM at runtime. This is done...

Introduction GraalVM is a revolutionary virtual machine designed to enhance the performance of Java and other languages while offering seamless polyglot capabilities. Developed by Oracle Labs, GraalVM provides Just-In-Time (JIT) and Ahead-of-Time (AOT) compilation,...
