Large Documents

Notta uses physical chunking cache technology to handle large documents, easily managing files with tens of thousands of lines.

What is Chunking

When opening a document, the system splits the content by line count into multiple "chunks," each independently cached to disk.

How Chunking Works

Original document (10,000 lines) split by line count:

• Chunk 1 → Lines 1–200
• Chunk 2 → Lines 201–400
• Chunk 3 → Lines 401–600
• ...
• Chunk 50 → Lines 9801–10000

Chunk Parameters

Paginated Browsing

Since the document is split into chunks, the editor displays one chunk at a time. The pagination control bar at the bottom provides navigation:

• PageUp / PageDown: Switch to previous/next page
• Scroll to boundary: Automatically switches to adjacent chunk when scrolling to the top or bottom
• Page indicator: Shows current page number and total pages

Re-chunking

During editing, if a chunk's content changes significantly (e.g., large paste or delete), the system automatically re-chunks:

• Auto-split: When chunk content exceeds 300 lines, it splits into two chunks
• Auto-merge: When chunk content falls below 50 lines, it attempts to merge with an adjacent chunk
• Empty chunk removal: Automatically cleans up empty chunks during editing

During re-chunking, the editor area shows a semi-transparent overlay with a "Re-chunking..." message, which disappears when complete.

Cache Management

Chunk caches are stored in the user data directory:

• Max cache size: 1 GB
• Auto-cleanup: The system manages cache automatically
