The PutSnowflakeInternalStage processor can upload a file to a Snowflake internal stage. Please note, that named stages needs to be created in your Snowflake account manually. See the documentation on how to set up an internal stage here. The processor requires an upstream connection and the incoming FlowFiles' content will be uploaded to the stage. A unique file name is generated for the file's staged file name. While the processor may be used separately, it's recommended to connect it to a StartSnowflakeIngest processor so that the uploaded file can be piped into your Snowflake table.
