Queries on AuthN and AuthZ for multi tenant Cassandra

We are using Cassandra 0.8.7 and building a multi-tenant cassandra platform where we have a common KS and common CFs for all tenants. By using Hector's virtual keyspaces, we are able to add modify rowkeys to have a tenant specific id. (Note that we do not allow tenants to modify/create KS/CF. We

I have cross dc replication set up using 0.8.7 with 3 nodes on each DC by following the +1 rule for tokens. I am seeing an issue where the insert into a DC happened successfully but on querying from cli or through Hector, i am not seeing the data being returned. i used cli on every node of both

Re: questions on frequency and timing of async replication between DCs

sstable2json

Hi, Is there a tool similar to sstable2json that can be used to convert data in commitlog to json? Or does sstable2json let us read the commitlog as well? Regards, smh.
