Method for seamless failback after planned failover

A system for seamless failback after a planned failover, the system comprising:

• one or more hardware processors;
• and
• one or more storage components storing instructions that, when executed by the one or more hardware processors, cause the one or more hardware processors to perform operations comprising:
• executing a reverse-and-swap command to transition a primary topic on a primary cluster from a mirror state to a production state and a corresponding secondary topic on a secondary cluster from the production state to the mirror state;
• based on the reverse-and-swap command, placing the primary topic and the corresponding secondary topic in a read-only state to allow the primary topic to synchronize all data;
• detecting that the primary topic is in a stopped mirror state after synchronizing all the data;
• after the primary topic is in the stopped mirror state, transitioning the primary topic to the production state;
• and
• after the transitioning of the primary topic, transitioning the corresponding secondary topic to the mirror state, the corresponding secondary topic mirroring data from the primary topic.

A machine-storage medium comprising instructions which, when executed by one or more hardware processors of a machine, cause the machine to perform operations for seamless failback after a planned failover, the operations comprising:

• executing a reverse-and-swap command to transition a primary topic on a primary cluster from a mirror state to a production state and a corresponding secondary topic on a secondary cluster from the production state to the mirror state;
• based on the reverse-and-swap command, placing the primary topic and the corresponding secondary topic in a read-only state to allow the primary topic to synchronize all data;
• detecting that the primary topic is in a stopped mirror state after synchronizing all the data;
• after the primary topic is in the stopped mirror state, transitioning the primary topic to the production state;
• and
• after the transitioning of the primary topic, transitioning the corresponding secondary topic to the mirror state, the corresponding secondary topic mirroring data from the primary topic.
