I have started working on a project in which I am using `Cassandra
database`.
Our production DBA's have setup `two cluster` and each cluster will have
`12 nodes`.
I will be using `Pelops client` to read the data from Cassandra database.
Now I am thinking what's the best way to create `Cluster` us
Folks, Any thoughts on this? I am still in the learning process. So any
guidance will be of great help.

I am designing the Column Family for our use case in Cassandra. I am
planning to go with Dynamic Column Structure.
Below is my requirement per our use case-
user-id column1123 (Column1-Value Column1-SchemaName LMD)
For each user-id, we will be storing column1 and its value and that val
= 'UTF8Type'
and comparator = 'BytesType'
and default_validation_class = 'UTF8Type'
and gc_grace = 86400
and column_metadata = [ {column_name : 'lmd', validation_class :
DateType}];
