Description
In this format, all data is represented as a single JSON Array.
Note
The JSONCompactColumns output format buffers all data in memory to output it as a single block which can lead to high memory consumption.
Example Usage
Columns that are not present in the block will be filled with default values (you can use input_format_defaults_for_omitted_fields setting here)
