> I want to use flink sql to write kafka messages directly to hdfs. The
> serialization and deserialization of messages are not involved in the middle.
> The bytes of the message directly convert the first field of Row. However,
> the current RowSerializationSchema does not support the conversion of bytes
> to VARBINARY. Can we add some special RowSerializationSchema and
> RowDerializationSchema ?
> ========================================================================
> Copied from FLINK-9963:
> Sometimes it might be useful to just read or write a single value into Kafka
> or other connectors. We should add a single-value SerializationSchemaFactory
> and single-value DeserializationSchemaFactory, the types below and their
> array types shall be considered.
> byte, short, int, long, float, double, string
> For the numeric types, we might want to specify the endian format.
> A string type single-value format will be added with this issue for future
> reference.
