Attaching to external data sources

Kuzu supports attaching/detaching to the following types of external data sources and databases:

  • External Kuzu databases: Attach to an external Kuzu database (possibly on a remote file system) and query that database in read-only mode via Cypher.
  • External RDBMSs | Attach to several relational databases, such as Postgres, DuckDB, and SQLite, and scan their tables with the LOAD FROM statement. This can simplify copying data from these sources into Kuzu and can also provide a basic functionality to do joint querying of the RDBMS and your local Kuzu database (or an external Kuzu database you attached to).
  • Iceberg: Attach to Iceberg tables
  • Delta Lake: Attach to Delta Lake tables
  • Unity Catalog: Attach to Delta Lake tables in Unity Catalog, an open and unified data goverance solution by Databricks.
