Discussion issue for thinking about how two clusters could be kept in eventual-sync:

Source/destination cluster tracking column to avoid looping cdc-sink'ed mutations
MVCC timestamp comparison to drop too-old events from source cluster
Conflict resolution detection / logic?

Playing with compare-and-set and deadlines in #86.

@bobvawter , is there anything else needed for this?

bobvawter commented 1 year ago

Yes, three-way merge via the userscript.

Is this addressed by LDR now? Or is it bi-directional sync between any combination of C2X?
