I have checked out several discussions and the TW7 High Availability admin guide about the TW HA and performance, but wasn't about to see the horizontal scalability for TW core. From the HA admin guide, only the failover scenario was dicussed. Is there any doc or best practice to allow TW Core to be load balanced and scale horizontally? Additionally, is there any TW build for cassandra as the data and model DB, so we can eliminate the PostgreSQL and pgpool completely from the architecture diagram. (So to use cassandra as persistence provider for both data and model DB.) Any ideas are appreciated. Thanks.
