Treating a specific topic as in-memory only

Hello,

I have a specific use-case where I am not allowed to persist a certain kind
of events. The events can be kept in memory, but not written to the disk.

Is this even possible with Kafka? Ideally I am looking for a per topic
configuration to disable the writing to disk.

The durability of the topic still need to come from re-syncing with the
replicas.

Thanks!
