Hi, I am new to spark and want to start contributing to Apache spark to know more about it. I found this JIRA to have "Standardized Join Types for DataFrames", which I feel could be a good starter task for me. I wanted to confirm if this is a relevant/actionable task and if I can start working on it. https://issues.apache.org/jira/browse/SPARK-26739
Thanks, Pooja Agrawal
