New Cache Plans

People

We have decided to rewrite the HTTP disk cache.

Design team:

  • ?

Implementation team:

  • ?

Design Requirements

  • All APIs should be async.
  • A crash should not invalidate the entire cache.

Performance Goals

  • Primary performance target is mobile - Android and Firefox OS. On-disk layout must optimize for this.
  • Make sure performance on spinning disks is good, but top performance here is not the priority.

API

API design goes here.

Locking

Locking plans go here. Clearly detail what locks the cache will have, and strategies to avoid lock contention in performance-critical situations.

On-Disk Layout

Clearly describe on-disk layout here.
