Redis with Full page cache module enabled : Full of page blocks in the DB

Hello ! I found something interesting after installing the full page cache module for Magento 2.4.2 and I would like to have your suggestions on that point .

Since I’ve launched the full page cache process, the Redis DB is always full (I put something like 20GB in maxmemory and I’m quickly reaching this limit ! Normally I’ve max 2GB when the full page cache is disabled) . I used redis-cli and UI tools to find what is filling the RAM and I found that there’s a huge amount of blocks filling Redis.

​

I’m a little bit confused : is it fully normal that there’re so many blocks ? Is there a way to disable this without impacting the rendering speed ?

​

Thanks for now 🙂
