Blake Eggleston commented on CASSANDRA-17103:
---------------------------------------------

Here you go: [https://github.com/apache/cassandra/pull/1845] I’ve created a 
feature branch for us and opened a PR against it.

This patch doesn’t include any CQL integration, that will be coming with 
Caleb’s work on CASSANDRA-17719. V1 also won’t include LWT integration, just 
the new txn syntax, although LWTs shouldn’t be difficult to add after Caleb’s 
CQL work. Caleb’s work is probably at the point where we get the paxos 
simulation running on top of it if we can make the simulation runner emit 
transaction queries.

I do expect to be addressing bugs as new functionality and testing exposes 
them, but I also think we should merge this sooner than later (ie: after I 
address any review feedback here) because:
 * Rebasing the metadata-persistence branch onto accord trunk after a change is 
very time consuming and the rebase can create it’s own bugs.
 * Caleb is already working off the metadata-persistence branches (Aleksey may 
be as well), and it would be good if we could keep development as close to the 
feature branch as possible.
 * Accord work should be an accord patch and a Cassandra patch. Keeping them 
separate means I do the integration work, which isn’t terrible, but I’d imagine 
it’s more efficient to do them together.
 * It’s going into a feature branch, not trunk. Not an excuse for buggy code, 
but it lessens the risk for now.
