Another way to look at this is that etcd has gained a huge amount of traction, at least in the modern app infrastructure / container space. This wouldn't be a limitation we would be accepting alone. If the demand is really there, we wouldn't be alone in needing to solve it. I wouldn't consider it a blocker. > > > - Can etcd handle big transactions? > > Xiang says that there's a 1 MB limit on transactions by default, which > can be increased.

Do you have any thoughts on next steps? a detailed look at how our existing schemas and some example transactions would be mapped to etcd? My gut reaction is that this is probably the right direction unless we can identify blockers. If we get to the point of a migration, I'd be willing to join an effort of locking a small group in a room to do the migration as quick as possible to help keep OVN on track. -- Russell Bryant
