#action ⇒ `String`

Specifies what action to take when writing to a table with preexisting data. Valid values: append, merge, truncate, drop.

Returns:

(String)

#additional_options ⇒ `Hash<String,String>`

Specifies additional options passed to the Snowflake connector. If options are specified elsewhere in this node, this will take precedence.

Returns:
