AutoLoader - handle spark write transactional (_SUCCESS file) on ADLS

Spark write method (df.write.parquet) to parquet files is transactional. I mean after write is sucessfull file _SUCCESS is created in path where parquet files was loaded.

Is it possible to configure AutoLoader to load parquet files only in case when write is done with success (_SUCCESS file was appeared) ?

I think my question wasn't understood correctly. I meant AutoLoader as the data loading tool provided by Databricks (https://docs.databricks.com/en/ingestion/auto-loader/index.html).

AutoLoader has set of different options to setup (https://docs.databricks.com/en/ingestion/auto-loader/options.html) but I don't find any option to help me achive resault which I described in this topc. Any ideas how to resolve my problem?
