# Enable Spline tracking.
# For Spark 2.3+ we recommend the codeless approach to enable Spline - by setting spark.sql.queryExecutionListeners
# (See: examples/README.md)
# Otherwise execute the following method to enable Spline manually.
sc._jvm.za.co.absa.spline.harvester \
    .SparkLineageInitializer.enableLineageTracking(spark._jsparkSession)

# Execute a Spark job as usual:
spark.read \
    .option("header", "true") \
    .option("inferschema", "true") \
    .csv("data/input/batch/wikidata.csv") \
    .write \
    .mode('overwrite') \
    .csv("data/output/batch/python-sample.csv")
