Hi All, It is great to know that Cassandra column family can accommodate 2 billion columns per row! I was reading about how Cassandra stores the secondary index info internally. I now understand that the index related data are stored in hidden CF and each node is responsible to store the keys of data that reside on that node only.
I have been using secondary index for a low cardinality column called "product". There can only be 3 possible values for this column. I have a four node cluster and process about 5000 records per second with a RF 2. My question here is, what happens after the number of columns in hidden index CF exceeds 2 billion? How does Cassandra handle this situation? I guess, one way to handle this is to add more nodes to the cluster. I am interested in knowing if any other solution exist. Thanks, Kamal
