jhorstmann opened a new pull request #8686:
URL: https://github.com/apache/arrow/pull/8686
This makes it much easier to analyze parquet files, for example by
processing the output with other command line tools like `jq`.
I'm opening this as a draft for now since I'd like some feedback on whether
this should be the default or whether the dependency on `serde_json` should be
optional.
Example output:
```
$ parquet-read parquet-testing/data/alltypes_plain.parquet 2 | jq .
{
"id": 4,
"bool_col": true,
"tinyint_col": 0,
"smallint_col": 0,
"int_col": 0,
"bigint_col": 0,
"float_col": 0,
"double_col": 0,
"date_string_col": "03/01/09",
"string_col": "0",
"timestamp_col": "2009-03-01 01:00:00 +01:00"
}
{
"id": 5,
"bool_col": false,
"tinyint_col": 1,
"smallint_col": 1,
"int_col": 1,
"bigint_col": 10,
"float_col": 1.100000023841858,
"double_col": 10.1,
"date_string_col": "03/01/09",
