There was a short talk about xtdb in the recent 'rubbing a database on it' conference: https://www.hytradboi.com/2022/baking-in-time-at-the-bottom-...

The talk expands on what "bitemporal" means in this context, namely, separate "valid" and "audit" time dimensions. The discussion upthread is a good example: if you accidentally mark down inventory in the wrong location and you find out later, you should backdate the fix to when you did the count -- this is the 'valid' dimension, but the fact that you changed it today should also be recorded so it can be reviewed later -- this is the 'audit' dimension.
