-----------------------------------
Assignee: Michael Fong
> Better Cassandra sink documentation
> -----------------------------------
>
> Key: FLINK-4498
> URL: https://issues.apache.org/jira/browse/FLINK-4498
> Project: Flink
> Issue Type: Improvement
> Components: Cassandra Connector, Documentation
> Affects Versions: 1.1.0
> Reporter: Elias Levy
> Assignee: Michael Fong
>
> The Cassandra sink documentation is somewhat muddled and could be improved.
> For instance, the fact that is only supports tuples and POJO's that use
> DataStax Mapper annotations is only mentioned in passing, and it is not clear
> that the reference to tuples only applies to Flink Java tuples and not Scala
> tuples.
> The documentation also does not mention that setQuery() is only necessary for
> tuple streams.
> The explanation of the write ahead log could use some cleaning up to clarify
> when it is appropriate to use, ideally with an example. Maybe this would be
> best as a blog post to expand on the type of non-deterministic streams this
> applies to.
> It would also be useful to mention that tuple elements will be mapped to
> Cassandra columns using the Datastax Java driver's default encoders, which
> are somewhat limited (e.g. to write to a blob column the type in the tuple
> must be a java.nio.ByteBuffer and not just a byte[]).
