Is there a way to take the first 1000 rows of a Spark Dataframe?

Question

I am using the randomSplitfunction to get a small amount of a dataframe to use in dev purposes and I end up just taking the first df that is returned by this fu

Answer 1

The method you are looking for is .limit.

Returns a new Dataset by taking the first n rows. The difference between this function and head is that head returns an array while limit returns a new Dataset.

Example usage:

df.limit(1000)

Answer 2

Limit is very simple, example limit first 50 rows

val df_subset = data.limit(50)
