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
df = spark.createDataFrame(
[(14, "Tom"), (23, "Alice"), (16, "Bob")], ["age", "name"])
df.tail(2)
# [Row(age=23, name='Alice'), Row(age=16, name='Bob')]
