Abstract
Systems and methods are directed to seamless failback after an unplanned failover. The method involves executing a truncate-and-restore command on a primary topic of a primary cluster, performing checks on a secondary topic to ensure it is a mirror topic in a stopped state with valid identifiers and offsets, and transitioning the primary topic to immutable state. The method further includes comparing sequence numbers to ensure safe truncation, truncating partitions to match the secondary topic's log end offsets, and clamping consumer group offsets. The primary topic is then converted to a mirror state, enabling active mirroring. A reverse command is then executed to complete the failback process, restoring the primary topic to a writable state.
