NEW QUESTION 36
A user is loading JSON documents composed of a huge array containing multiple records into Snowflake. The user enables the strip__outer_array file format option What does the STRIP_OUTER_ARRAY file format do?
- A. It removes the outer array structure and loads the records into separate table rows,
- B. It removes the trailing spaces in the last element of the outer array and loads the records into separate table columns
- C. It removes the last element of the outer array.
- D. It removes the NULL elements from the JSON object eliminating invalid data and enables the ability to load the records
Data Size Limitations
The VARIANT data type imposes a 16 MB size limit on individual rows.
For some semi-structured data formats (e.g. JSON), data sets are frequently a simple concatenation of multiple documents. The JSON output from some software is composed of a single huge array containing multiple records. There is no need to separate the documents with line breaks or commas, though both are supported.
If the data exceeds 16 MB, enable the STRIP_OUTER_ARRAY file format option for the COPY INTO
table command to remove the outer array structure and load the records into separate table rows:
copy into table
file_format = (type = 'JSON' strip_outer_array = true);
