> For analytics & auditing purposes it becomes essential to serve different access
patterns than that modeled from a partition key fetch perspective, although a limited reads
are needed by users but if enabled cluster wide it will require index write for every row
written on that table on every single node on every DC even the one which may be serving read
operations. A user may not want to have indices built on Transactional DC on every write,
that computation and disk utilization may not be useful as the Analytics may possibly be performed
on other DC.
> It will be a plus to have analytics / auditing workload built inside Cassandra itself
using native secondary indices / SASI indices / Stratio by creating indices for a specific
datacenter and not having to ship off data to other index stores like Elasticsearch through
application.
