Job callers currently lose the server's structured progress when describing, listing, or waiting for a job. Expose Rust and Python progress snapshots and optional wait observers using the existing backend poller. Python supports callbacks, a caller-owned tqdm-like bar, or `progress=True`; `status()` still returns a string and the default wait behavior is unchanged. Preserve unknown progress fields and phases from newer servers, and report omitted counters as unknown. Each wait calibrates a caller-owned bar from its first complete snapshot, then uses a high-water mark within the same execution epoch; a new epoch or smaller plan resets the bar. ETA is best-effort and omitted for missing, stale, paused, or incompatible samples. Newly submitted index and refresh handles forward observers through their freshness wrapper while retaining successful-wait read consistency. The Jobs guide includes draft Python/Rust snapshot and observer examples for release; TypeScript progress support remains tracked under ENT-3500. Validation on the development EC2 host: the initial 11 Python progress tests, REST fixture caller, and two Rust progress regressions passed. After fixing freshness-wrapper forwarding, rebuilt the Python extension and ran two submitted-handle Python tests plus the new Rust refresh and index regressions (one test each); all passed. Strict Clippy, rustfmt, and targeted Ruff passed. The final commit only wraps the new guide section in an MDX draft and clarifies language support. Repository-wide Ruff reports 48 existing findings in six unchanged docs/web-tests files. This publishes the SDK portion of ENT-3500. Server-side live-split and terminal-progress changes and the combined server/SDK end-to-end scenario remain in progress. Refs ENT-3500. BREAKING CHANGE: Rust struct literals for `JobInfo` must add `progress: None`, `phase: None`, and `paused: false`. Literals for `JobDescription` must add `progress: None`, `phase: None`, `queue_reason: None`, `waiting_for_job_id: None`, and `paused_at_millis: None` when that metadata is unavailable. Existing Python calls remain compatible.

The ultimate multimodal data platform for AI/ML applications.
LanceDB is designed for fast, scalable, and production-ready vector search. It is built on top of the Lance columnar format. You can store, index, and search over petabytes of multimodal data and vectors with ease. LanceDB is a central location where developers can build, train and analyze their AI workloads.
Demo: Multimodal Search by Keyword, Vector or with SQL
