Primary goal: end-to-end point cloud logging to 3D scene, with a functional and fast query engine that has the desired interface.

Sub-issues:

• Arrow entity UI components #386
• Out of order Arrow ingestion #393
• polars::Dataframe-based query result for populating Scene:s #390
• Tracking issue: Feature parity Arrow-based SDK logging #387

Things we can work on in parallel now:

• Arrow data store
• Python SDK
• Rust SDK

Things we can work on once the Arrow data store is done

• Data UI
• Table UI
• Scene population

Arrow data store

For the arrow data store (and query engine), follow https://www.notion.so/rerunio/Arrow-Table-Design-cd77528c77ae4aa4a8c566e2ec29f84f. We can probably work in parallel on the main table and on the batching.
