Hello!  
I see in the output INFO MEMORY:  
`maxmemory_policy:noeviction`

can i change this policy?

`127.0.0.1:6379> info server`  
`redis_version:7.4.0`  
`dragonfly_version:df-v1.28.1`

as far as I understand - no!?

Hi @KleinenberG,

I don’t think Dragonfly allows changing the eviction policy on the fly while the server is running at the moment, but a server flag (and a restart of the server) can be used.

In the meantime, we don’t have the same eviction policies Redis has. We have only one `cache mode`, which is a sophisticated and efficient LRU + LFU combined algorithm.

- [Read more about Dragonfly’s cache mode](https://www.dragonflydb.io/blog/dragonfly-cache-design)
- [Configure Dragonfly with `--cache_mode=true`](https://www.dragonflydb.io/docs/managing-dragonfly/flags#--cache_mode)

After the change, the below is what I get. And Dragonfly would evict keys when the used memory is getting close to `maxmemory`.

```bash
dragonfly$> INFO MEMORY
# ...
cache_mode:cache
maxmemory_policy:eviction
# ...

```
