One CQL row per user, keyed off of the UUID.
Another table keyed off of email, with another column containing the UUID
for lookups in the first table. Only registration will require a
lightweight transaction, and only for the purpose of avoiding duplicate
email registration race conditions.
Thanks, I was actually thinking of doing that. Something along the lines of
CREATE TABLE user (
idtimeuuid PRIMARY KEY,
emailtext,
nametext,

);
CREATE TABLE user_email_index (
email text,

PRIMARY KEY (email, id)

And during registration, I would
It does sound right.
You might want to have additional session tracking id's, separate from the
user id, but that is an additional implementation detail, and could be
external to Cassandra. But the approach you describe accurately describes
what I would do as a first pass, at least.

Cool. BTW, what do you mean by have additional session tracking ids? What’d
that be for?

You’re right. I didn’t catch that. No need to have email in the PRIMARY KEY.
