Jiangjie Qin commented on FLINK-14807:
--------------------------------------
[~ykt836] not necessarily. Two major difference makes this much easier than a
generic exactly once sink.
# We also own the "target system" which the sink emits records to.
# We probably don't have to tolerate the client failure case. i.e. if the
client is gone, the job can stop.
These two difference will probably make the implementation significantly
simpler.
> Add Table#collect api for fetching data to client

> 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.
