Hi Pandula, As per the BAM team secondary index should index the already existing data as well. When we create a secondary index on a cassandra column family,It should start the indexing process immediately so there shouldn't be a requirement to publish data again.
I agree with your concern about load handling but as per Cassandra doc [1], It won't be a problem.But we have to do a test run to make sure.
