test_table path: s3a://test_bucket/test_table/
df = spark_session.sql("SELECT * FROM test_table")
df.count() # produce row number 1000
#####S3 operation######
s3 = boto3.client("s3")
s3.put_object(
Bucket="test_bucket", Body="", Key=f"test_table/"
)
#####S3 operation######
df.write.insertInto(test_table, overwrite=True)
# Same goes to df.write.save(mode="overwrite", format="parquet",
