Redis edit

Useful miscellany from the redis-db list

Memory usage of redis suspiciously exceeds size of dump edit

  • What types of keys do you have? How big are they? What are they storing?
  • In INFO output: memory fragmentation ratio, used_memory_rss
  • Debug memory use with DEBUG OBJECT <key>

Sets edit

  • It's not documented, but you can use ZINTERSTORE and ZUNIONSTORE with SETs in Redis, they act as though their members all have a score of 1.
  • BLPOP will block the connection until a new item is available to pop from a list
