Add an option to print output in JSON format. in the parquet-read binary. Having json output allows for easy analysis using tools like [jq](https://stedolan.github.io/jq/). This PR builds on the changes implemented in https://github.com/apache/arrow/pull/8686 and incorporates the suggestions in that PR. **Changelog** * Update all three binaries `parquet-schema`, `parquet-rowcount` and `parquet-read` to use [clap](https://github.com/clap-rs/clap) for argument parsing * Add `to_json_value()` method to get `serde_json::Value` from `Row` and `Field` structs (Thanks to @jhorstmann for these changes!) * parquet-schema: * Convert verbose argument into `-v/--verbose` flag * parquet-read: * Add a new flag `-j/--json` that prints the file contents in json lines format * The feature is gated under the `json_output` cargo feature * Update documentation and README with instructions for running * The binaries now use version and author information as defined in Cargo.toml Example output: ``` ❯ parquet-read cities.parquet 3 --json {"continent":"Europe","country":{"name":"France","city":["Paris","Nice","Marseilles","Cannes"]}} {"continent":"Europe","country":{"name":"Greece","city":["Athens","Piraeus","Hania","Heraklion","Rethymnon","Fira"]}} {"continent":"North America","country":{"name":"Canada","city":["Toronto","Vancouver","St. John's","Saint John","Montreal","Halifax","Winnipeg","Calgary","Saskatoon","Ottawa","Yellowknife"]}} ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
