Want inputs about super column family vs map/list
Hi All,
There are two ways to achieve this :
1. Using super column family:
raman | atul | bhuvan
---------------------------
1234 | 5678 | 2345
OR
Using single Collection column :
Phone Number
---------------------------
Map <raman,1234>
<bhuvan,2345>
<atul,5678>
I would like to know which approach would be better in the below use cases :
1. First Case - Frequent complete map Update
2. Second Case - Frequent complete map Read
3. Frequent Update only for specific fields.
4. Frequent Read only for specific fields.
Also is there any way to configure cassandra-stress tool for testing this
scenario?
Thanks & Regards,
Bhuvan

Hmm, I have same issue.
I would like to know how you are able migrating data from RDBMS to
cassandra in this way., i.e. making column's value as column name.
Are you using some programming script or datastax scoop support for this?

Super columns have been not-recommended for use for about five years now.
