This system doesn’t support interactive transactions does it? In that the whole read / write set needs to be known up front before a transaction can start being processed? I know that systems like FoundationDB and Calvin/Fauna work similarly and get incredible performance because sequencing is so much easier / lock free. I think those two systems couldn’t be adapted for interactive transactions really (without client side retries) but maybe warp could be which is cool!

FoundationDB does interactive transactions.

Last I checked, the entire transaction is built in memory (and famously has a five-second time limit), so while you can make multiple round trips, it's not quite as useful as with other databases.

The 5s timeout is annoying sometimes, but it does really support interactive transactions in the exact same sense that PostGres and MySQL do.
