If you just use the Cassandra default mapper, you can also use the class defined in the Stack Overflow answer https://stackoverflow.com/a/45073242/1630604 to generate the DDL from your entities.

Thanks for pointing me to the secondary index info. I'll have a look. greetings Daniel On Tue, 26 Sep 2017 at 09:42 kurt greaves <k...@instaclustr.com<mailto:k...@instaclustr.com>> wrote: If you've created a secondary index you simply query it by specifying it as part of the where clause. Note that you should really understand the drawbacks of secondary indexes before using them, as they might not be incredibly efficient depending on what you need them for. http://www.wentnet.com/blog/?p=77 and https://pantheon.io/blog/cassandra-scale-problem-secondary-indexes might help.

I successfully got the DataStax driver and the mapper up and running, but can't seem to figure out how to set secondary indexes through the mapper. I also can't seem to find anything related to indexes in the mapper sources - am I missing something or is this missing from the client library? greetings Daniel
