You can load and process Parquet files in Observable Framework by using FileAttachment alongside parquet-wasm. This approach enables efficient parsing of columnar data for high-performance analytical tasks.

Yes, you can visualize Apache Arrow tables directly using Plot marks and Inputs.table. This integration allows you to render columnar data efficiently without converting it to standard JavaScript objects.

The best way to query Parquet files with DuckDB is by integrating the query engine directly with your loaded columnar data. This setup provides optimized, high-performance analysis for large datasets.

Yes, Observable Framework supports loading Apache Arrow IPC files. You can load data directly from .arrow files using the FileAttachment API to handle columnar datasets efficiently.

You can manipulate Apache Arrow tables directly in JavaScript by using the direct Arrow API. This allows you to create and modify columnar data structures in memory for analytics.

You should use Apache Arrow instead of JSON when handling large datasets that require high-performance analytics. Arrow's columnar memory format provides efficient loading and processing for visualization and querying.
