Hello there, it's a new year, and a new season to tag Google Summer of Code ideas. If you would like to mentor a student to contribute to Beam via GSoC, and have some ideas, feel free to start tagging them so they will participate with the Apache Foundation's application.
If you've never done GSoC before, try reading this: https://community.apache.org/gsoc.html If you have questions, feel free to ask here. There's a few of us who've mentored students in previous years. To tag a JIRA issue, you may use the "gsoc2021" label, and the issue will be included with the ASFs list of ideas. Thanks! -P.
