You are tasked with building a process to incrementally ingest data from a file uploaded to cloud object storage at the end of an inventory process. The schema of the file is expected to change over time, and the ingestion process should automatically handle these changes. Fill in the blanks in the following Auto Loader command to ensure successful execution:

spark.readStream
  .format("cloudfiles")
  .option("_______","csv")
  .option("_______", 'dbfs:/location/checkpoint/')
  .load(data_source)
  .writeStream
  .option("_______",' dbfs:/location/checkpoint/')
  .option("_______", "true")
  .table(table_name)
