  The way the change is currently written, it shouldn’t invalidate the current 
cache contents (though we can still flag it as risky).

  Considering that insight, throwing the entire cache for Terms away in one go 
would seem to be a very bold move. Can we make that "% based rollout of the new 
version" with our current setup and config, or are code change needed to make 
this possible?
  
  At the very least, the patch that introduces the new formatter version (and 
possibly invalidates the current keys in the process?) should probably be 
flagged as a risky patch to watch out for during the next deployment.

[Wikidata-bugs] [Maniphest] T252595: Consider ways to invalidate FormatterCache when things go wrong

2020-09-28 Thread Addshore
Addshore added a comment.


  @toan and I had a chat about this ticket this morning and summarized we said 
that:
  
  - For formatter cache version patches need a few tweaks but all look like the 
right direction
- We have never tried "dumping" the whole formatter cache at once before, 
but predict that it should just result in a small spike in slowness (and more 
db load) as the first spike of repopulation gets dealt with and then a long 
small tail
- One thing that came up was that using WANCache inside the formatter cache 
would probably result in a slightly better internal situation when and if this 
were to happen.
- It will be very hard to figure out what any of this would look like in 
advance of trying it.
- One thing that could be done to make possible usage less interesting 
would be some sort of % based rollout of the new version.
  
  Regarding the idea of allowing action=purge to purge the formatter cache:
  
  - We discussed this on the client side
- The usage tracking mechanisms don't have an index on page_id, so getting 
from the page to the entities used would not be ideal.
- We also doubted the value in this approach given the main issue is when 
incident happen, and in this case the formatter cache version would need to be 
incremented instead.
  - We also discussed this on the repo side
- This would be easier, but less useful.
- Purging the formatter cache for Q64 when doing action=purge on Q64 is 
odd, as that cache is not actually used in the page rendering at all.
  
  Perhaps we could look at the above ideas further if we ever need more 
solutions in this area, but for now not having them is probably fine, as we 
have a version key in the cache key now.
