Use Impala to Query Cassandra

Hi everyone,
   I'd like to float an idea today: adding support for querying Cassandra
data from Impala.
Impala can already query and analyze data from sources like HBase and Kudu.
I think we could add Cassandra as a new data source to further enrich
Impala's query and analytics ecosystem.

As far as I know, if your data lives in Cassandra, the options available
today are Presto for OLAP analysis [1], Trino for OLAP analysis [2], or
Spark for offline/batch analysis [3]. I believe Impala should have an
equivalent capability as well.
I'd love to hear your thoughts.

Hi Guo, thanks for floating this idea.  We have not specifically discussed Cassandra integration.  I am not familiar with Cassandra, thus I don't have a clear picture of the specific use cases for integrating a no-sql database.  What is your vision for how this integration would work?

Another option would be to use Impala's JDBC table functionality.  It would require some setup work to figure out how to do that, but it may fulfill your needs.

Thanks,
Jason
