# Docs: "Streaming Data & Progressive Rendering" Guide

# Docs: "Streaming Data & Progressive Rendering" Guide

## Objective
Create a comprehensive guide in `learn/guides/datahandling/Streaming.md` explaining the new Streaming Data architecture implemented in Epic #9089.

## Content
The guide should cover:
1.  **Concept:** Why stream? (Time-to-First-Byte vs Time-to-First-Render, Memory O(1)).
2.  **Architecture:**
    -   `Neo.data.proxy.Stream` (App Worker side).
    -   `TextDecoderStream` & `ReadableStream` (Browser API).
    -   Chunking & Batching (Performance).
3.  **Store Integration:**
    -   `proxy` config vs `url`.
    -   Progressive Loading (Events: `load` firing multiple times).
    -   Impact on Grids (Scrollbar updates).
4.  **Format:** JSONL (NDJSON) requirements.
5.  **Visuals:** Mermaid sequence diagram showing the flow of data from Fetch -> Stream -> Chunk -> Store -> Grid.

## Location
-   File: `learn/guides/datahandling/Streaming.md`
-   Tree: Add under `Guides -> Data Handling`.

## Tasks
- [ ] Create `learn/guides/datahandling/Streaming.md`.
- [ ] Update `learn/tree.json`.
- [ ] Verify formatting in Portal (optional but good practice).

### @tobiu - 2026-02-10T19:41:42Z

**Input from Gemini 3 Pro:**

> ✦ I have created the "Streaming Data & Progressive Rendering" guide.
> 
> ### Deliverables
> 1.  **`learn/guides/datahandling/Streaming.md`**: Comprehensive guide covering the problem (TTFR, Memory), the solution (Stream Proxy, Chunking, Progressive Loading), implementation details, and performance benchmarks. Includes a Mermaid sequence diagram.
> 2.  **`learn/tree.json`**: Added the new guide to the navigation tree under "Data Handling".
> 
> This completes the documentation requirements for the streaming initiative.
