Apache Iceberg emerged as the winner of the 2024-25 table format war — Netflix, Apple, LinkedIn, Stripe, Airbnb all converged on it. Databricks acquired Tabular (founded by Iceberg co-creator Ryan Blue) for over $1B in June 2024, bringing Delta Lake and Iceberg under one roof. Apache Hudi takes its own path through Onehouse, while Apache Paimon (born from the Flink team) defines a new category called "streaming lakehouse." For processing engines, Spark 4 (Spark Connect) and Flink 2 lead; for query engines, Trino, Presto, DuckDB, and ClickHouse share the field; for transformations, dbt is the standard; for catalogs, Unity Catalog, Polaris, and BigLake compete. This essay maps the 2026 lakehouse landscape — table formats, engines, catalogs, commercial services, plus Korean and Japanese case studies — in one sweep.

Apache Iceberg가 2024-25년 테이블 포맷 전쟁의 승자로 떠오르면서 Netflix·Apple·LinkedIn·Stripe·Airbnb가 모두 그 위에 모였고, Databricks는 2024년 6월 Iceberg 공동 창시자 Ryan Blue의 Tabular를 $1B 이상으로 인수해 Delta Lake와 Iceberg를 한 지붕 아래로 끌어들였다. 한쪽에서는 Apache Hudi가 Onehouse라는 상용화 회사를 통해 자기 길을 가고, Flink 팀이 만든 Apache Paimon이 스트리밍 레이크하우스라는 새 카테고리를 정의한다. 처리 엔진은 Spark 4(Spark Connect)와 Flink 2가, 쿼리 엔진은 Trino·Presto·DuckDB·ClickHouse가, 변환은 dbt가, 카탈로그는 Unity Catalog·Polaris·BigLake가 나눠 들고 있다. 이 글은 2026년 데이터 레이크하우스의 풍경을 — 테이블 포맷, 엔진, 카탈로그, 상용 서비스, 한국·일본 사례까지 — 한 호흡으로 정리한다.

Resend has made react-email the de-facto standard for indie startups, but Maizzle has quietly captured Tailwind teams, MJML stays the dependable open standard, and Stripo / BEE / Stensul / Unlayer keep eating the marketing-team market. This guide walks the four buckets — code, component, drag-and-drop, SaaS — and covers Outlook dark-mode hell, MIME multipart, accessibility, and the slow death of AMP for Email, in one sitting.

Resend의 react-email이 인디 스타트업의 사실상 표준이 되었지만, Maizzle의 Tailwind 워크플로, MJML의 컴포넌트 모델, Foundation/Cerberus의 클래식 패턴, Stripo·BEE·Stensul의 드래그앤드롭 SaaS는 각각의 자리에서 살아남았다. 이 글은 코드 / 컴포넌트 / 드래그앤드롭 / SaaS 네 분류를 가로지르며, Outlook의 다크모드 지옥, MIME multipart의 plain-text 의무, 그리고 거의 죽었지만 아직 안 죽은 AMP for Email까지 한 호흡으로 정리한다.
