IMPLEMENTATION

Viewers responsible for this format

Arrow IPC preserves a columnar schema and record batches for efficient interchange. Anyfile opens supported file or stream layouts through DuckDB-Wasm and presents their rows in the shared table.

Common question

Are Arrow and Feather always identical?

Feather v2 uses Arrow IPC, while older or specialized files can differ from the layouts the viewer accepts.
