Hi, I wrote the current cluster implementation, but I understand it has many limitations. If I would do it again, I would now use a different approach, more like what MongoDB does: use replication for failover and read scalability, and use partitioning for write scalability. The current implementation is basically replication, but it is on the SQL level, which is problematic. I think replication would be better done on a lower level, for example on the file system or table level. But that means the current solution would have to be re-written almost from scratch. Unfortunately, I will not have time to do that in the near future. My priority is (besides fixing bugs of course, and support) to work in the new storage engine (MVStore).
