> Key: FLINK-25199
> URL: https://issues.apache.org/jira/browse/FLINK-25199
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Task
> Affects Versions: 1.12.7, 1.13.5, 1.14.3
> Reporter: Timo Walther
> Assignee: Piotr Nowojski
> Priority: Critical
> Labels: pull-request-available
> Fix For: 1.15.0, 1.13.6, 1.14.4
>
>
> It seems {{fromValues}} that generates multiple rows does not emit any
> watermarks:
> {code}
> StreamTableEnvironment tEnv = StreamTableEnvironment.create(env);
> Table inputTable =
> tEnv.fromValues(
> DataTypes.ROW(
> DataTypes.FIELD("weight", DataTypes.DOUBLE()),
> DataTypes.FIELD("f0", DataTypes.STRING()),
> DataTypes.FIELD("f1", DataTypes.DOUBLE()),
> DataTypes.FIELD("f2", DataTypes.DOUBLE()),
> DataTypes.FIELD("f3", DataTypes.DOUBLE()),
> DataTypes.FIELD("f4", DataTypes.INT()),
> DataTypes.FIELD("label", DataTypes.STRING())),
> Row.of(1., "a", 1., 1., 1., 2, "l1"),
> Row.of(1., "a", 1., 1., 1., 2, "l1"));
> DataStream<Row> input = tEnv.toDataStream(inputTable);
> {code}
> {{fromValues(1, 2, 3)}} or {{fromValues}} with only 1 row works correctly.
