Talk Info:
We present Floe, a SQL query service designed for modern data lakehouse architectures. Floe combines three core components: FloeSQL, a compute engine for executing sophisticated SQL over open table formats; Floecat, an open-source catalog-of-catalogs that unifies metadata across Apache Iceberg and Delta Lake ecosystems; and Floescan, an indexing service that enables fine-grained data skipping within Parquet files.
Floe is motivated by the fragmentation of today’s lakehouse stack across formats, catalogs, and query engines. By bringing together high-performance query execution, unified metadata access, and file-level indexing, Floe applies proven architectural principles from Yellowbrick to the open data ecosystem, enabling faster and more consistent analytics on lakehouse data.
