Fundamentals of data lake architecture — storage layout, partitioning, format selection, and lifecycle management.

AWS Glue provides native Iceberg support for cataloging, ETL, and built-in table maintenance — but production lakehouses hit limitations fast. This guide covers Glue catalog configuration, ETL best practices, compaction tuning, common pitfalls, and how a dedicated control plane fills the operational gaps.
Apache Iceberg on AWS S3 is the standard architecture for open lakehouses. This guide covers how Iceberg's metadata hierarchy maps to S3 objects, the AWS services ecosystem (Glue, Athena, EMR, Redshift, S3 Tables), configuration best practices, performance optimization, table maintenance, and the operational components needed for production deployments.
A technical comparison of the seven major Apache Iceberg catalogs — Hive Metastore, AWS Glue, Apache Polaris, Project Nessie, Databricks Unity Catalog, Apache Gravitino, and Lakekeeper — across protocol support, access control, multi-engine interoperability, credential vending, and production readiness.
Eight optimization layers for data platform engineers running BI, ad-hoc SQL, and aggregation pipelines on Apache Iceberg — from partition design and file sizing through compaction, routing, and continuous maintenance.
A deep technical guide to managing the metadata layer that makes Apache Iceberg fast — snapshots, manifests, metadata.json files, and Puffin statistics — covering expiration, consolidation, orphan cleanup, and the sequencing that prevents production incidents.
Iceberg tables degrade silently — small files from streaming, unsorted data, fragmented manifests, accumulated delete files. Each one caps query speed regardless of engine. Six concrete optimization layers, how they interact, and how autonomous maintenance keeps every table at peak performance.
Data lakes, warehouses, and lakehouses are not interchangeable — each has hard limits the others cannot cover. A practical guide for platform leaders: where each architecture wins, where it fails, cost and governance trade-offs, and how to choose (or combine) them in 2026.
Compaction keeps Apache Iceberg lakehouses fast and lean — but every tool approaches it differently. A side-by-side look at nine production options: LakeOps, AWS Glue, Amazon S3 Tables, Snowflake, Google BigLake, Cloudera, Starburst, Dremio, and Databricks.
Every data lake starts with a promise of unlimited flexibility — and most end up as a swamp. Stale files, broken schemas, no observability, and engineers spending more time maintaining pipelines than analyzing data. Apache Iceberg fixed the reliability gap. A lakehouse control plane fixes everything else. A practical guide to the full transition — component by component.
Compaction is the most impactful operation in an Apache Iceberg lakehouse — and the hardest to get right at scale. File merging is the easy part. Knowing when to trigger it, what sort strategy to apply per table, how to avoid conflicting with other maintenance, and how to do it without spinning up expensive JVM clusters — that is the real problem. A breakdown of what modern compaction actually requires.
AI agents issue SQL iteratively, repeat query templates at high frequency, and need sub-second responses from tables designed for batch workloads. This post covers what breaks when agents hit a production Iceberg lake — and the five infrastructure layers that fix it: MCP connectivity, guardrails, multi-engine routing, self-optimizing storage, and closed-loop feedback.
See how a 350TB data lake shrank to 230TB in 10 minutes by removing stale data—saving 34% in AWS S3 costs and proving the need for a control plane.
Apache Iceberg delivers speed, but without a control plane snapshots pile up, costs surge, query take more time — starting with expiration.
