So. We did a few things better than the industry to this day. HA is a spectrum. Transparent masking of all failures in any state of arbitary SQL transaction is on the far right side of that spectrum.

To directly answer your question: go look at where 'replication' was on rdbms 14 years ago. PostgreSQL? MySQL?

Comdb2 is open sourced
