Invalidation

Tag Caching

Objects are assigned an auto-incrementing version number
When an object changes, the cache is updated with that version number
Caches that refer to multiple object-types, keep a reference to the versions of each object the cache refers to.

ex.

  • User created user_v=0
  • User renamed user_v=1
  • ProjectUsers adds user proj_v=1
  • ProjUserCache is tagged with user_v=1,proj_v=1
