> *First time proposing new update so apologies if I missed anything*
> Currently the DataSet API only has the ability to output data received from
> Cassandra as a source in as a Tuple. This would be allow the data to be
> output as a custom POJO that the user has created that has been annotated
> using Datastax API. This would remove the need of very long Tuples to be
> created by the DataSet and then mapped to the custom POJO.
>
> The changes to the CassandraInputFormat object would be minimal, but would
> require importing the Datastax API into the class. Another option is to make
> a similar, but slightly different class called CassandraPojoInputFormat.
> I have already gotten code for this working in my own project, but want other
> thoughts as to the best way this should go about being implemented.
>
> //Example of its use in main
> CassandraPojoInputFormat<CustomCassandraPojo> cassandraInputFormat = new
> CassandraPojoInputFormat<>(queryToRun, defaultClusterBuilder,
> CustomCassandraPojo.class);
> cassandraInputFormat.configure(null);
> cassandraInputFormat.open(null);
> DataSet<CustomCassandraPojo> outputTestSet =
> exEnv.createInput(cassandraInputFormat, TypeInformation.of(new
> TypeHint<CustomCassandraPojo>(){}));
>
> //The class that I currently have set up
> [^CassandraPojoInputFormatText.rtf]
>
> Will make another Jira Issue for the Output version next if this is approved
