This is a repackaged open-source software product wherein additional charges apply for support and for providing it in a simple consumable AMI. DuckDB is an in-process analytical database that's designed to handle large datasets and complex queries efficiently. It's intended to be an alternative to data warehouses, providing high performance without the same level of complexity or cost. It stores data in a compressed columnar format, which provides the best performance for large-scale aggregations. This is in contrast to a transactional database, which is optimized for high-frequency writes and typically stores data as rows (tuples) to support that. DuckDB has no external dependencies, neither for compilation nor during run-time. DuckDB does not run as a separate process but is completely embedded within a host process.
