pip install duckdbpip install scylla-driverpip install duckdbpip install scylla-driverPython data engineers use DuckDB to run fast analytical SQL queries directly on Parquet files in a data lake without a database server. `duckdb.query('SELECT * FROM parquet_scan("s3://bucket/file.parquet")')` returns an Arrow table convertible to pandas — enabling complex aggregations on large files in seconds without loading them fully into memory.
Python data engineers use ScyllaDB as a Cassandra replacement when latency is critical — the `cassandra-driver` library works unchanged since ScyllaDB is wire-compatible. Engineers migrating from Cassandra to ScyllaDB typically see P99 write latency drop from milliseconds to microseconds without any Python code changes.
