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
