[jira] [Created] (ARROW-10297) [Rust] Parameter for parquet-read to output data in json format

Jörn Horstmann created ARROW-10297:
--------------------------------------

             Summary: [Rust] Parameter for parquet-read to output data in json format
                 Key: ARROW-10297
                 URL: https://issues.apache.org/jira/browse/ARROW-10297
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Rust
            Reporter: Jörn Horstmann


When analyzing data related issues I found it really helpful to filter or portprocess the contents of parquet files on the command line using jq (https://stedolan.github.io/jq/manual/).

Currently the output of parquet-read is in a custom json-like format, I propose to add an optional flag that outputs the contents as json using the serde_json library. This should probably be behind a feature gate to avoid adding the dependency for everyone.
