About

OLake Fusion is a self-hosted application for maintaining Apache Iceberg tables in data lakehouses. It automates scheduled table compaction, merging small data files and converting delete files to improve table layout as data is continuously ingested, updated, or deleted. Users can configure maintenance at the table level and schedule Lite, Medium, and Full compaction tiers, review table health and file metrics, and track maintenance runs and logs through a web UI. Fusion connects to Iceberg catalogs, including AWS Glue, Hive Metastore, JDBC, and REST-based catalog implementations such as Nessie, Polaris, Unity Catalog, and Lakekeeper, and can maintain tables created outside OLake. It is deployed on Docker or Kubernetes in a team's cloud or on-premises environment, and is designed for data engineers and platform teams operating analytical lakehouses with Apache Iceberg.

About

R2 SQL is Cloudflare’s serverless, distributed analytics query engine (currently in open beta) that enables you to run SQL queries over Apache Iceberg tables stored in R2 Data Catalog without needing to manage your own compute clusters. It is built to efficiently query large volumes of data by leveraging metadata pruning, partition-level statistics, file and row-group filtering, and Cloudflare’s globally distributed compute infrastructure to parallelize execution. The system works by integrating with R2 object storage and an Iceberg catalog layer, so you can ingest data via Cloudflare Pipelines into Iceberg tables, and then query that data with minimal overhead. Queries can be issued via the Wrangler CLI or HTTP API (with an API token granting permissions across R2 SQL, Data Catalog, and storage). During the open beta period, using R2 SQL itself is not billed, only storage and standard R2 operations incur charges.
