DataBricks 中 pandas.DataFrame.tail 的等价物是什么

What is the equivalent of pandas.DataFrame.tail in DataBricks

DataBricks 中 pandas.DataFrame.tail 的等价物是什么?我在文档中搜索了一下,但没有找到任何相关功能。

DataBricks 显然使用的是 pyspark.sql 数据帧,而不是 pandas

# Index the df if you haven't already
# Note that monotonically increasing id has size limits
from pyspark.sql.functions import monotonically_increasing_id
df = df.withColumn("index", monotonically_increasing_id())

# Query with the index
tail = sqlContext.sql("""SELECT * FROM df ORDER BY index DESC limit 5""")
tail.show()

请注意,这很昂贵并且没有发挥 Spark 的优势。
