Description
Differs from the JSONColumns format in that it also contains some metadata and statistics (similar to the JSON format).
Example usage
Example:
{
"meta":
[
{
"name": "num",
"type": "Int32"
},
{
"name": "str",
"type": "String"
},
{
"name": "arr",
"type": "Array(UInt8)"
}
],
"data":
{
"num": [42, 43, 44],
"str": ["hello", "hello", "hello"],
"arr": [[0,1], [0,1,2], [0,1,2,3]]
},
"rows": 3,
"rows_before_limit_at_least": 3,
"statistics":
{
"elapsed": 0.000272376,
"rows_read": 3,
"bytes_read": 24
}
}For the JSONColumnsWithMetadata input format, if setting input_format_json_validate_types_from_metadata is set to 1,
the types from metadata in input data will be compared with the types of the corresponding columns from the table.
