True or False: Reader Accounts are able to extract data from shared data objects for use outside of Snowflake.

  1. True
  2. False

Answer(s): A



True or False: Loading data into Snowflake requires that source data files be no larger than 16MB.

  1. True
  2. False

Answer(s): B

Explanation:

By default, COPY INTO location statements separate table data into a set of output files to take advantage of parallel operations. The maximum size for each file is set using the MAX_FILE_SIZE copy option. The default value is 16777216 (16 MB) but can be increased to accommodate larger files. The maximum file size supported is 5 GB for Amazon S3, Google Cloud Storage, or Microsoft Azure stages. To unload data to a single output file (at the potential cost of decreased performance), specify the SINGLE = true copy option in your statement. You can optionally specify a name for the file in the path.
