Since .foreachBatch() is "hijacking" the stream and executing arbitrary code in it, do I need to specify Output mode and Path:

(df.writeStream
.format("delta")
.trigger(availableNow = True)
.option("checkpointLocation", "check_point_location")

.foreachBatch(data_load)

.outputMode('update')
.option('path', output_filepath)
.start()
)

 Or I can do it without it:

(df.writeStream
  .format("delta")
  .trigger(availableNow = True)
  .option("checkpointLocation", "check_point_location")

  .foreachBatch(data_load)

  .start()
  
)

code for load_data:

def data_load(df, batchId):
  (target.alias("target").merge(
    source = df.alias("source"),
    condition = "target.key = source.key"
  ).whenMatchedUpdateAll()
  .whenNotMatchedInsertAll()
  .execute()
  )
