> If you run a database without reading the documentation then you're the dangerous part

I think that covers almost all the whole dev population, for what I see in relation with RDBMS. Lucky us most RDBMs shield the mistakes in their usage, a lot.

That is why I see is "dangerous" to call ephemeral/eventual stores as "db". Marketing/positioning have impacts...

All databases are ephemeral if the person running it don't read the docs. Your comment is hence fully redundant, as opposed to the default single-node install of any DBMS.
