Mix of IM Rowstore with Disk Columnstore

@adam, thanks for the quick reply

What isolation levels are supported?
Can a single transaction with a single commit do update 2 tables, one in IM rowstore, second in disk columnstore?
MVCC, Joint Clock / single commit serial number between two stores, Joint recovery- do they exist?

Also, this forum post (Move the data in memory (rowstore) to disk) says the opposite - MOVE data from rowstore to columnstore is IMPOSSIBLE, which kind of means “NO” to all my questions… strange…

Can you elaborate? maybe point to some documentation

Thanks
