Nodetool drain and nodetool flush are similar commands. Both commands flush
memtable to disk. The difference is a nodetool drain will make C* stop

with this standard is a must. There are three parts to this:
(1) Controls and audit of user logins / forcing re-login when session times

all changes to an entity over its lifetime.

Instead of thinking of data as global mutable state,
You are right. One of the products that I was involved with had an “eAudit”
feature baked into the application layer tracking every change and capturing
user, changed value, affected attribute / column, an event type (insert,
