> It would be nice to convert flink table to java List so that I can do other
> data manipulation in client side after execution flink job. For flink
> planner, I can convert flink table to DataSet and use DataSet#collect, but
> for blink planner, there's no such api.
> EDIT from FLINK-14807:
> Currently, it is very unconvinient for user to fetch data of flink job unless
> specify sink expclitly and then fetch data from this sink via its api (e.g.
> write to hdfs sink, then read data from hdfs). However, most of time user
> just want to get the data and do whatever processing he want. So it is very
> necessary for flink to provide api Table#collect for this purpose.
> Other apis such as Table#head, Table#print is also helpful.
