You should post the whole CQL query you try to execute! Why don't you use a
native JSON type for your JSON data?

Hi,
I have a json data as shown below.

Hi Alain,
Thanks for your response and the links.
I've also checked "Time series data model and tombstones".
Is it safe to use TWCS in C* 3.9?
Thanks in advance.

With regards to having DCs for specific workloads, it would be nice to have
per DC indexes. See https://issues.apache.org/jira/browse/CASSANDRA-12663.

Lucene/Elassandra and Spark serve different purposes.
Lucene & Elassandra are designed for real-time queries that have predicates
on columns not in the Cassandra primary key (i.e. searches). For example if
you have a "person" table with person_id as the primary key but you want to

The problem with adhoc queries on casssandra (with spark or not) is the
partition model of cassandra that needs to be respected to avoid full scan
queries (the link you mentioned explains all of them). With FiloDB, which
works on cassandra, you can pushdown predicates of the partition key and
