Crate parquet_layout 

Binary that prints the physical layout of a parquet file

NOTE: due to this binary’s use of the deprecated parquet::format module, it will no longer be maintained, and will likely be removed in the future. Alternatives to this include parquet-cli and parquet-viewer.

Install

parquet-layout can be installed using cargo:

cargo install parquet --features=cli

After this parquet-layout should be available:

parquet-layout XYZ.parquet

The binary can also be built from the source code and run as follows:

cargo run --features=cli --bin parquet-layout XYZ.parquet
