Hello. I have a erasure pool and I didn't turn on compression at the beginning.
Now I'm writing new type of very small data and overhead is becoming an issue.
I'm thinking to turn on compression on the pool but in most
filesystems it will effect only the new data. What is the behavior in
ceph?

The same. You need to rewrite all your data

You can do that without user interaction too, if you recreate all
affected OSDs. That way the data on the OSD is recreated and thus
compressed because it is "new".
