tail

Returns the last num rows as a list of Row.

Syntax

tail(num: int)

Parameters

Parameter	Type	Description
num	int	Number of records to return. Will return this number of records or all records if the DataFrame contains less than this number of records.

Returns

list: List of rows.

Notes

Running tail requires moving data into the application's driver process, and doing so with a very large num can crash the driver process with OutOfMemoryError.

Examples

Python

df = spark.createDataFrame(
    [(14, "Tom"), (23, "Alice"), (16, "Bob")], ["age", "name"])

df.tail(2)
# [Row(age=23, name='Alice'), Row(age=16, name='Bob')]
