Syntax
Connect-Parquet -FlattenObjects bool
Data Type
bool
Default Value
true
Remarks
Set FlattenObjects to true to flatten object properties into columns of their own. Otherwise, objects nested in arrays are returned as strings of JSON. To generate the column name, the 本製品 concatenates the property name onto the object name with a dot.
For example, you can flatten the nested objects below at connection time:
[ { "grade": "A", "score": 2 }, { "grade": "A", "score": 6 }, { "grade": "A", "score": 10 }, { "grade": "A", "score": 9 }, { "grade": "B", "score": 14 } ]When FlattenObjects is set to true and FlattenArrays is set to 1, the preceding array is flattened into the following table:
Column Name | Column Value |
grades.0.grade | A |
grades.0.score | 2 |
