2025-2026 Guide to Learning about Apache Iceberg, Data Lakehouse & Agentic AI

The data world is evolving fast. Just a few years ago, building a modern analytics stack meant stitching together tools, ETL pipelines, and compromises. Today, open standards like Apache Iceberg, modular architectures like the data lakehouse, and emerging patterns like Agentic AI are reshaping how teams store, manage, and use data.

But with all this innovation comes one challenge: where do you start?

This guide was created to answer that question. Whether you're a data engineer exploring the Iceberg table format, an architect building a lakehouse, or a developer curious about AI agents that interact with real-time data, this resource will walk you through it. No hype. No fluff. Just a curated directory of the best learning paths, tools, and concepts to help you build a practical foundation.

We will break down the links into many categories to help you find what you are looking for. There is more content beyond what I have listed here and here are two good directories where you can find more content to explore.

The Data Lakehouse

The idea behind a data lakehouse is simple: keep the flexibility of a data lake, add the performance and structure of a warehouse, and make it all accessible from one place. But turning that idea into a working architecture takes more than just buzzwords. In this section, you'll find tutorials, architectural guides, and practical walkthroughs that explain how lakehouses work, when they make sense, and how to get started, whether you’re running everything on object storage or looking to unify data access across teams and tools.

Apache Iceberg

Apache Iceberg is the table format that makes data lakehouses actually work. It brings support for ACID transactions, schema evolution, time travel, and scalable performance to your cloud storage, without locking you into a vendor or engine. If you’ve ever wrestled with Hive tables or brittle partitioning logic, this section is for you. Here, you'll find beginner-friendly resources, deep dives into metadata and catalogs, and hands-on guides for working with Iceberg using engines like Spark, Flink, and Dremio.

What are Lakehouse Open Table Formats

Table formats are the backbone of the modern lakehouse. They define how data files are organized, versioned, and transacted, bringing warehouse‑level reliability to open storage. This section explores what makes formats like Apache Iceberg, Delta Lake, and Apache Hudi so important. You’ll learn how they handle schema evolution, partitioning, and ACID transactions while staying engine‑agnostic, ensuring your data remains open, performant, and ready for any workload.

Apache Iceberg Tutorials

Getting hands‑on is the fastest way to learn Apache Iceberg. In these tutorials, you’ll spin up local environments, run your first SQL commands, and connect Iceberg tables with catalogs like Apache Polaris or engines like Spark and Dremio. Each guide walks you through setup, basic operations, and troubleshooting so you can move from theory to practice without friction.

Iceberg Migration Tooling and Ingestion

Moving existing datasets into Apache Iceberg doesn’t have to be painful. This section highlights migration patterns, ingestion tools, and automation workflows that make it easier to adopt Iceberg at scale. You’ll find step‑by‑step resources covering snapshot‑based migrations, bulk ingests, and hybrid models that help teams modernize data lakes while minimizing downtime and duplication.

Iceberg Catalogs

A table format is only as useful as the catalog that organizes it. Iceberg catalogs manage metadata, access control, and engine interoperability, essential pieces of a production lakehouse. In this section, you’ll explore the expanding catalog ecosystem, from open implementations like Apache Polaris to commercial and hybrid options. These resources explain how catalogs enable discoverability, governance, and smooth multi‑engine coordination across your data environment.

Apache Iceberg Table Optimization

Keeping Iceberg tables fast requires more than good schema design. Over time, data fragmentation, small files, and metadata sprawl can slow queries and inflate costs. The articles in this section show how to maintain healthy tables through compaction, clustering, and automatic optimization. You’ll also learn how modern platforms like Dremio manage this maintenance autonomously so performance tuning doesn’t become a full‑time job.

Iceberg Technical Deep Dives

Once you understand the basics, the real fun begins. These deep dives unpack how Iceberg works under the hood, covering metadata structures, query caching, authentication, and advanced performance topics. Whether you’re benchmarking, extending the format, or building your own catalog integration, this section will help you understand Iceberg’s architecture and internal mechanics in detail.

The Future of Apache Iceberg

Apache Iceberg continues to evolve alongside emerging workloads like Agentic AI and next‑generation file formats. This section looks ahead at what’s coming; new format versions, engine integrations, and evolving standards such as Polaris and REST catalogs. If you want to stay informed on where Iceberg is heading and how it fits into the broader open‑data movement, start here.

Agentic AI

Agentic AI is a new class of systems that don’t just answer questions, they take action. These agents make decisions, follow workflows, and learn from outcomes, but they’re only as smart as the data they can access. That’s where open lakehouse architectures come in. This section explores the intersection of data architecture and autonomous systems, with content focused on how to power agents using structured, governed, and real-time data from your Iceberg-based lakehouse. From semantic layers to zero-ETL federation, you'll see what it takes to build AI that isn't just reactive, but genuinely useful.
