the configuration is done by the methods above.
the only configuration possible is setting the writeMode or consistence and
if you have multiple output format, this configuration can be different between
outputs
> Kudu connector to read/write from/to Kudu
> -----------------------------------------
>
> Key: BAHIR-99
> URL: https://issues.apache.org/jira/browse/BAHIR-99
> Project: Bahir
> Issue Type: New Feature
> Components: Flink Streaming Connectors
> Affects Versions: Flink-1.0
> Reporter: Rubén Casado
> Assignee: Rubén Casado
> Priority: Major
> Fix For: Flink-Next
>
>
> Java library to integrate Apache Kudu and Apache Flink. Main goal is to be
> able to read/write data from/to Kudu using the DataSet and DataStream Flink's
> APIs.
> Data flows patterns:
> Batch
> - Kudu -> DataSet<RowSerializable> -> Kudu
> - Kudu -> DataSet<RowSerializable> -> other source
> - Other source -> DataSet<RowSerializable> -> other source
> Stream
> - Other source -> DataStream <RowSerializable> -> Kudu
> Code is available in https://github.com/rubencasado/Flink-Kudu
