Timo Walther updated FLINK-9852:
--------------------------------
Description:
Currently, only a table source can be created using the unified table
descriptors with {{tableEnv.from(...)}}. A similar approach should be supported
for defining sinks or even both types at the same time.
I suggest the following syntax:
{code}
tableEnv.connect(Kafka(...)).registerSource("name")
tableEnv.connect(Kafka(...)).registerSink("name")
tableEnv.connect(Kafka(...)).registerSourceAndSink("name")
{code}
A table could then access the registered source/sink.
We need to introduce a new update-mode property in order to distinguish between
append, retract, and upsert table sources and sinks.
