# Persistence
# =====================================================

# RDB (Snapshot) Persistence
# save <seconds> <changes>
# Save the DB on disk:
save 900 1      # after 900 sec (15 min) if at least 1 key changed
save 300 10     # after 300 sec (5 min) if at least 10 keys changed

# allkeys-lfu - evict any key according to LFU algorithm
# volatile-lru - evict keys with TTL set, LRU algorithm
# volatile-lfu - evict keys with TTL set, LFU algorithm
# volatile-ttl - evict keys with TTL, expire soonest first
