• Description

admin_settings:
  cache:
    fallback_behavior: string

• Cache fallback behavior.

• By default the MUMC uses a hybrid LRU/LFU RAM cache

• The fallback_behavior is used when:

  1. Once the cache is too full for the next entry
  2. minimum_age is used to establish which entries are eligible for removal
  3. MUMC then tries to remove the oldest entry meeting the minimum_age with the lowest number of hits
  4. If no entrys meet the minimum_age or all entries all entries meeting the minimum_age have the same number of cache hits; then the fallback_behavior is used

• Setting DEBUG: 1 will print the cache statistics to help determine the best cache settings (i.e. size, fallback_behavior, and minimum_age)

• Fallback To:

  • FIFO - First In First Out (oldest entry is removed)
  • LFU - Least Frequently Used (first entry with the lowest number of hits is removed)
  • LRU - Least Recently Used (first entry with the oldest last access time is removed)
