> In Snowflake the Boolean type is represented by the Boolean data type
> ([https://docs.snowflake.com/en/sql-reference/data-types-logical]), but Spark
> rely on the default JdbcDialect to generate the mapping which maps _Boolean_
> to _BIT(1)_
> This should be probably handled by a dialect specific to Snowflake.
