chrevanthreddy opened a new pull request, #19309: URL: https://github.com/apache/hudi/pull/19309
### Describe the issue this Pull Request addresses This PR adds the full RFC document for **RFC-109: Native Vector Search Support in Apache Hudi**, following the RFC number claim merged in #19303. It links the RFC into the registry (`rfc/README.md`) and adds the design document plus architecture/read/write diagrams. Umbrella tracking issue: apache/hudi#19094 ### Summary and Changelog - Add `rfc/rfc-109/rfc-109.md` — the RFC-109 design document covering: goals/non-goals, architecture, the IVF + RaBitQ index algorithm, the metadata-table posting-block storage model, bootstrap/write path, read path, and maintenance/rebalancing/cleaner semantics. - Add `rfc/rfc-109/diagrams/` — architecture overview, read path, and write/maintenance SVG diagrams referenced by the doc. - Update `rfc/README.md` — link the existing RFC-109 registry row (`UNDER REVIEW`) to the new document. This is a **docs-only** change. No production code, tests, or build files are touched. The implementation lands separately as the focused PR series tracked under #19094 (child issues #19096–#19105). ### Impact None on runtime, build, or existing functionality — documentation only. Establishes the reviewable design of record for the vector index feature so the community can evaluate architecture separately from implementation. ### Risk Level none Docs-only; no code paths, dependencies, or CI behavior affected. ### Documentation Update This PR *is* the documentation update: it introduces the RFC-109 design document and diagrams and links them from the RFC index. No user-facing site docs change until the feature is implemented and merged. ### Contributor's checklist - [x] Read through [contributor's guide](https://hudi.apache.org/contribute/how-to-contribute) - [x] Change Logs and Impact described above - [x] Necessary doc changes done or have another open PR (this PR is the doc) - [x] For large changes, please consider breaking it into sub-tasks under an umbrella issue (tracked in #19094) -- This is an automated message from the Apache Git Service.
