Motivation

Some issues have been observed in production where the cache appears to get into a broken state, including a cascading eviction of all models.

Modifications

  • Fix cache accounting in loading failure + unload case
  • Eagerly remove expired failure records from cache
  • Correct misworded log message
  • Log some internal cache values along with published instance records, to facilitate further diagnoses
  • Increase load failure expiry times

Result

Hopefully fixed cache accounting issue
