class DefaultSource extends RelationProvider with SchemaRelationProvider with CreatableRelationProvider with StreamSinkProvider with DataSourceRegister

Snowflake Source implementation for Spark SQL Major TODO points:

  • Add support for compression Snowflake->Spark
  • Add support for using Snowflake Stage files, so the user doesn't need to provide AWS passwords
  • Add support for VARIANT
