Details

(Whiteboard: [genai])

Current implementation uses fixed limits:

  • MAX_URLS_PER_TAB = 1000 (increased from 500 based on feedback)
  • DEFAULT_TTL_MS = 30 minutes

Reviewer noted potential quadratic situation: 1000 tabs × 1000 URLs = 1M normalized URLs.

Note: MAX_URLS_PER_TAB is URLs per individual tab (links on a page), not total tabs.

Scope

  • Add telemetry to track real-world ledger sizes
  • Evaluate if 1000 is the right limit based on data
  • Consider per-tab MRU/LFU eviction instead of hard cap
  • Adjust limits based on usage data

Reference

  • D274523 reviewer feedback
  • Related: Bug 2005415 (scheduled vs lazy cleanup)

Acceptance Criteria

  • Telemetry added to track ledger sizes in real usage
  • Sizing strategy documented based on data
  • Eviction strategy reviewed and optimized if needed
