Explore comprehensive Scala 2 functional programming fundamentals grounded in mathematical theory. This guide covers pure functions that ensure determinism and referential transparency, enabling equational reasoning and safe parallelization. Discover higher-order functions like map, filter, and fold that accept or return functions as first-class values. Master function composition techniques using compose and andThen operators to build complex pipelines. Learn currying—the mathematical transformation of multi-argument functions into sequences of single-argument functions. Understand immutability principles, side-effect elimination, and how these concepts form the backbone of scalable, testable Scala applications through category theory and lambda calculus foundations.

This implementation demonstrates building Multi-Agent RAG systems using AWS Bedrock's Amazon Large Language Models (LLMs) integrated with LangGraph for intelligent document processing (IDP). The system implements document relevance grading using the Titan Express LLM and integrates the Chroma vector database with Amazon Titan embeddings for semantic search, and processes articles into optimised chunks for RAG performance. LangGraph's workflow orchestration creates adaptive AI agents that automatically retry and transform queries up to 3 times with sophisticated conditional routing logic based on document relevance scores. The multi-agent architecture utilises specialised Bedrock models for answer generation, document grading, and query rewriting, creating a production-ready system with LangChain Expression Language (LCEL) integration for seamless component chaining.

This post delves into AWS S3 Access Points, highlighting how they simplify managing data access at scale by providing dedicated access policies per application.
