----------------------------------
Hi [~rmetzger]
Thank you for your reminder, recently I noticed the new contribution process.
Some of these tickets are created by myself, some are what I am implementing,
and some are what I originally intended to implement, but there is currently no
time to implement them.
I will further evaluate them and release some tickets that I might not
implement for the time being. Please give me some time.
> Method equals() in RowTypeInfo should consider fieldsNames
> ----------------------------------------------------------

> Key: FLINK-12848
> URL: https://issues.apache.org/jira/browse/FLINK-12848
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Planner
> Affects Versions: 1.7.2
> Reporter: aloyszhang
> Assignee: vinoyang
> Priority: Major
> Labels: pull-request-available
> Time Spent: 0.5h
> Remaining Estimate: 0h

> Since the `RowTypeInfo#equals()` does not consider the fieldNames , when
> process data with RowTypeInfo type there may comes an error of the field
> name.
> {code:java}
> String [] fields = new String []{"first", "second"};
> TypeInformation<?>[] types = new TypeInformation[]{
> Types.ROW_NAMED(new String[]{"first001"}, Types.INT),
> Types.ROW_NAMED(new String[]{"second002"}, Types.INT) };
> StreamExecutionEnvironment execEnv =
> StreamExecutionEnvironment.getExecutionEnvironment();
> StreamTableEnvironment env =
> StreamTableEnvironment.getTableEnvironment(execEnv);
> SimpleProcessionTimeSource streamTableSource = new
> SimpleProcessionTimeSource(fields, types);
> env.registerTableSource("testSource", streamTableSource);
> Table sourceTable = env.scan("testSource");
> System.out.println("Source table schema : ");
> sourceTable.printSchema();
> {code}
> The table shcema will be
> {code:java}
> Source table schema :
> root
> |-- first: Row(first001: Integer)
> |-- second: Row(first001: Integer)
> |-- timestamp: TimeIndicatorTypeInfo(proctime)
> {code}
> the second field has the same name with the first field.
> So, we should consider the fieldnames in RowTypeInfo#equals()
