Features are disclosed for managing multiple hosts that stream sequential data to nodes for propagation. The hosts can include a primary host and a failover host that each store a replica of the sequential data. A computing device can monitor the hosts and identify the occurrence of a failover event for the primary host. For example, the computing device may determine the schema has been modified. The computing device can further determine to failover to the failover host based on the failover event. The computing device can insert a flip task into the stream of sequential data for the primary host. The insertion of the flip task may be automatic. Further, each node reading from the stream of sequential data for the primary host may encounter the flip task and failover to the failover host at the same logical position but a different absolute position.
