   @belugabehr Although I am not very familiar with this area, but what happens if multiple HMS are running in HA? Wouldn't this solution mean, that potentially the order of the notification events will change? Two HMS are running HMS 1 gets id range 1-10, HMS 2 gets 11-20. Then openTxn notification goes to HMS 2 and allocateWriteId notification goes to HMS1. The sequence of the ids will not represent the sequence of the events. Wouldn't this mess up acid table replication?
