今回の検証に利用したマニフェスト https://github.com/kota2and3kan/lakehouse-samples/blo b/2026-07-15-ochacafe/sample-b/demo.md
突然ですが
Lakehouse が気になってます
Lakehouse を手軽に試したい
壊しても怒られない Lakehouse がほしい
ということで
作ってみました
Kubernetes (kind) DuckDB (Query Engine) Demo 環境概要 SeaweedFS (Object Storage)
Lakekeeper (REST Catalog) Iceberg Table Iceberg Table Iceberg Table Catalog Operations Read/Write Table Data
構成要素 1: Kubernetes (Platform) Kubernetes (kind)
構成要素 2: SeaweedFS (S3 互換の Object Storage) Kubernetes (kind) SeaweedFS
(Object Storage)
構成要素 3: Lakekeeper (Iceberg REST Catalog) Kubernetes (kind) SeaweedFS (Object
Storage) Lakekeeper (REST Catalog)
構成要素 4: DuckDB (Query Engine) Kubernetes (kind) SeaweedFS (Object Storage)

Demo https://github.com/kota2and3kan/lakehouse-samples/blo b/2026-07-15-ochacafe/sample-b/demo.md
まとめ
まとめ • ローカル環境の Kubernetes (kind) 上に Lakehouse っぽい ものを作れた。 •
実際に Catalog や Object Storage の中身を見ながら検証が できる。 • 壊しても怒られない。 • Let’s enjoy!
Thank you!
