> I'm using Cassandra to store data coming from Spark and intended for being consumed by a javascript front end.
> To avoid unnecessary field name mappings I have decided to use mixed case fields in Cassandra. I also happily leave it to Cassandra to jsonify the data (using SELECT JSON ...) so my scala/play web server can send the results from Cassandra straight through to the front end.
> I noticed however that all mixed case fields (that were created with quotes as Cassandra demands) end up having a double set of quotes
> {code}
> create table user(id text PRIMARY KEY, "firstName" text);
> insert into user(id, "firstName") values ('b', 'Bill');
> select json * from user;
> [json]
> --------------------------------------
> {"id": "b", "\"firstName\"": "Bill"}
> {code}
> Ideally that would be:
> {code}
> [json]
> --------------------------------------
> {"id": "b", "firstName": "Bill"}
> {code}
> I worked around it for now by removing all "\""'s before sending the json to the front end.
