Mark the correct steps for saving the contents of a DataFrame to a Snowflake table as part of Moving Data from Spark to Snowflake?

Show Suggested Answer Hide Answer
Suggested Answer: C

Moving Data from Spark to Snowflake

The steps for saving the contents of a DataFrame to a Snowflake table are similar to writing from Snowflake to Spark:

1. Use the write() method of the DataFrame to construct a DataFrameWriter.

2. Specify SNOWFLAKE_SOURCE_NAME using the format() method.

3. Specify the connector options using either the option() or options() method.

4. Use the dbtable option to specify the table to which data is written.

5. Use the mode() method to specify the save mode for the content.

Examples

1. df.write

2. .format(SNOWFLAKE_SOURCE_NAME)

3. .options(sfOptions)

4. .option('dbtable', 't2')

5. .mode(SaveMode.Overwrite)

6. .save()

Snowflake, huh? I wonder if they have a special 'snow mode' for writing data. Maybe it'll make everything look like it's covered in a layer of frost. Wouldn't that be cool?

Ah, yes, the good old Spark to Snowflake data migration. I've done this dance a few times before. Option C seems to have all the right steps.

Hmm, let's see... I think option C looks the most straightforward. Plus, it has the word 'correct' in it, so it must be right. Easy peasy!

Wait, did we just get a question about saving data to Snowflake? I thought this was an exam on Spark, not a winter sports competition!
