Thank you. I believe that bidirectional replication will solve the ETL problem, if it can be configured to stream from a replica in the source/oltp cluster (to minimize network IO on the source cluster master db) to the master of the destination/olap cluster. The olap master can mirror the oltp data, but also use triggers to denormalize oltp tables.

One thing I'd like to see is the ability to sanitize/munge data from the source cluster before it is sent to the destination cluster, for masking sensitive data in the source cluster (PCI, HIPAA, etc).
