In-memory support availability

Hi Couchbase experts.

I am studying Couchbase for personal interest, and I started to wonder whether there is in-memory support available other than memchached bucket, as I understand that the memchached bucket does not support disk persistence, or does it? And is there any plans for in-memory support in the near future? It will be so thankful if someone can help me out.

Thanks

Do have a look at our docs on how we manage disk persistence.
