We've been running replication poll and we've got some answers, so I thought I would comment a little on the results of the poll and what our future plans with respect to replication is as a result of the feedback. As I commented in the previous post, there are some items that require a significant development effort, but the feedback we got helps us to prioritize.
The top five items from the poll above stands out, so I thought that I would comment on each of them in turn. The results of the poll were (when this post were written):
|Online check that Master and Slave tables are consistent||45.4%|
|Multi-source replication: replicating from several masters to one slave||36.3%|
|Multi-threaded application of data on slave to improve performance||29.2%|
|Conflict resolution: earlier replicated rows are not applied||21.0%|
|Semi-synchronous replication: transaction copied to slave before commit||20.3%|
