What to do in case of "Bloom filter" server failure?

Hello everyone,

There are two things I would like to ask about Redis’ “Bloom filter”.

1- Is Redis bloom filter data stored in cache? What happens in case of failure (server restarts, server crashes)? I want to keep the data in Bloom filter permanently.

2- Can the Redis bloom filter be created “distributedly” (replica sets) on docker?

Thank you.


  1. Like any other key, bloom filters are saved to an RDB file and reloaded in case of failure.
  2. Yes. Redis manages BF keys in a similar manner to other keys.
