If you can construct unique primary keys from the data you have, I'd suggest
you create your own custom primary keys instead of using UUIDs. It will be
easier for you to retrieve the records.
If you use UUIDs as your primary keys for a table, you need to have some kind
of index so that you can
The point is to have a unique, generated ID for each entity, to ensure
absolute uniqueness. In the old days each app had its own technique for
generating unique IDs. Now we have UUIDs, which are unique, but are
generated uniformly across systems and applications. Uniqueness is
guaranteed even if an
OK.
My question is more about what are the use case of any table uuid as
partition key.
Will appreciate inputs from others.

Hi Prem,
We have two tables, one with email id as partition key and other with
userid(uuid).
Please refer to www.killrvideo.com website. It is a great place to
understand how a web application is built on Cassandra.

Thanks Jay. Now this is great while creating the user. How does the user
change the details? let's say email id or password? How do you lookup the
user table?

We are designing a web application using Cassandra.
When a user signs on we create user info in user table with userid (uuid)
is primary and is responded back to UI.
UI uses this UUID for any future communications. UI can also get user id
when searched for an user detail
Hi,
I am trying to understand different use cases related to using UUID as the
partition key. I am sure I am missing something trivial and will be
grateful and you can help me understand this.
When do you use the UUID as the primary key? What can be a use case?
Since it is unique, how do you quer
