Summary: Document Spark explodeArray function behavior
Key: DATAFU-158
URL: https://issues.apache.org/jira/browse/DATAFU-158
Project: DataFu
Issue Type: Improvement
Reporter: Shay Elbaz
The `explodeArray` function counts the size of the output array by executing
Spark job internally on the input data. This should be documented, so users
could choose whether to persist the input DataFrame, or not.
