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 command to remove the outer array structure and load the records into separate table rows:
copy into from @~/
file_format = (type = 'JSON' strip_outer_array = true); https://docs.snowflake.com/en/user-guide/semistructured-considerations.html

True or False: Snowflake charges additional fees to Data providers for each share they create.
