Robert Metzger updated FLINK-10873:
-----------------------------------
Component/s: API / Table SQL
> Remove tableEnv in DataSetConversions#toTable and
> DataStreamConversions#toTable
> -------------------------------------------------------------------------------
>
> Key: FLINK-10873
> URL: https://issues.apache.org/jira/browse/FLINK-10873
> Project: Flink
> Issue Type: Improvement
> Components: API / Table SQL
> Reporter: Jeff Zhang
> Assignee: Hequn Cheng
> Priority: Major
>
> What I would like to achieve is to change the following code
> {code}
> val table = data.flatMap(line=>line.split("\\s"))
> .map(w => (w, 1))
> .toTable(tEnv, 'word, 'count)
> {code}
> to this
> {code}
> val table = data.flatMap(line=>line.split("\\s"))
> .map(w => (w, 1))
> .toTable('word, 'count)
> {code}
> The only change is that tableEnv is removed in method toTable. I think the
> second piece of code is more readable. We can create TableEnvironment based
> on the ExecutionEnvironment of DataSet/DataStream rather than asking user to
> pass it explicitly.
