For cloud native architecture, if one instance have crashed, it can failover to another available instance. it is better to make instance stateless, we should also make transaction log saved in database or other sharable storage. So we consider about developing SPI for transaction log persistence and recovery, and narayana is an implement for that. For atomikos, we also plan to extend it.
