[GSoC 2026] Call for Mentors - Native RoaringBitmap Integration for Apache Fluss

Hi everyone,

I am preparing a GSoC 2026 proposal for Apache Fluss titled "The Bitmap
Bridge: End-to-End RoaringBitmap Integration for Apache Fluss."

The project aims to promote BITMAP to a first-class logical type, integrate
it with the existing AggregationMergeEngine, and implement pushdown via
applyAggregates(). A working prototype is available on my public fork, and
a FIP discussion is currently active on this list.

FIP thread: https://lists.apache.org/thread/z9dwyg81cs3bt7yssb4n3vg17o767r5s
Prototype:
https://github.com/Prajwal-banakar/fluss/tree/RoaringBitmap-prototype

To participate in GSoC 2026, Fluss requires a JIRA issue in the Apache GSoC
project and a PPMC member to serve as a mentor. Would any PPMC member be
willing to mentor this project and assist with creating the JIRA ticket?

Best regards,
Prajwal Banakar
