Add a Unique ID Column to a Spark DataFrame
Add a unique ID column to a Spark DataFrame. The Spark
monotonicallyIncreasingId function is used to produce these and is
guaranteed to produce unique, monotonically increasing ids; however, there is
no guarantee that these IDs will be sequential.
Usage
sdf_with_unique_id(x, id = "id")Arguments
- x
- An object coercable to a Spark DataFrame (typically, a
tbl_spark). - id
- The name of the column to host the generated IDs.
