What are you using for replication?
-Kevin
Hi Kevin,
I set up a master-master asynchronous replication of one database with bucardo 4.4.5 and testing right now 4.99.3.
I know the standard settings when a conflict between same id rows comes up :
source - the rows on the "source" database always "win" (in a conflict, we copy rows from source to target)
target - the rows on the "target" database always win
skip - any conflicted rows are simply not replicated. Not recommended
for most cases.
random - each database has an equal chance of winning each time
latest - the row that was most recently changed wins
abort - the sync is aborted on a conflict You can also provide custom
conflict handlers to allow you to use business logic for better conflict
resolution.
I have not found info or examples about the custom option yet, and still on the search ...
Cheers,
Amador A.
