Correct. Only individual operations are atomic, and ordering of
insertions is not guaranteed.

I think there were some logged Jira issues to allow grouping of
operations into what seems to amount to transactions, which could help
a lot here... but I can't find it now (or maybe it has only been
discussed so far?).
If I understand this correctly, it would just mean that you could send
a sequence of operations, to be completed as a unit (first into
journal, then into memtable etc).
