Partitioning determines how much data every query must scan. Apache Iceberg's hidden partitioning and partition evolution change the game — but choosing the wrong strategy still creates performance cliffs. A practical guide to transforms, sizing, evolution, and avoiding the small-files trap.
Puffin files store table-level statistics — NDV sketches and custom blobs — that query engines use for join ordering, split planning, and cost-based optimization. A practical guide to how they work, how to collect them, how they go stale, and how to keep them accurate at scale.
A practical guide to optimizing Apache Iceberg queries and table maintenance with Trino — covering scan planning, predicate pushdown, file pruning, Trino-side tuning, maintenance procedures, physical layout optimization, and how a dedicated control plane eliminates JVM overhead while adding cross-engine intelligence.
How to route queries across Trino, Spark, DuckDB, Snowflake, Athena, and Flink on shared Iceberg tables — covering the architecture of a SQL routing proxy, dialect translation, routing strategies, table-aware optimization, and the tooling that makes it work.
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.
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.
ExternalQueryFlux is a universal SQL proxy and multi-engine query router in Rust—one access layer in front of Trino, DuckDB, StarRocks, and Athena with routing, dialect translation, and observability.
