Hi Hangxiang,
感谢您的回应。
下面是该问题的关键代码，main_stream表是流数据源，数据事件流频约每笔500ms~1s，目前尝试将t1minStream和t5minStream
assignTimestampsAndWatermarks(WatermarkStrategy.noWatermarks())是不会产生这问题造成作业失败了，但输出会有数据丢失。
如有其他思路，麻烦你了。
String t1minSql = "SELECT rowtime, key, id, AVG(num) OVER w_t1min AS avg_t1min
FROM main_stream WINDOW w_t1min AS (PARTITON BY key ORDER BY rowtime RANGE
BETWEEN INTERVAL ‘1’ MINUTES PRECEDING AND CURRENT ROW)";
Table t1minTable = tableEnv.sqlQuery(t1minSql);
String t5minSql = "SELECT rowtime, key, id, AVG(num) OVER w_t5min AS
avg_t5min FROM main_stream WINDOW w_t5min AS (PARTITON BY key ORDER BY rowtime
RANGE BETWEEN INTERVAL ‘5’ MINUTES PRECEDING AND CURRENT ROW)";
Table t5minTable = tableEnv.sqlQuery(t5minSql);
DataStream<Row> t1minStream = tableEnv.toChangelogStream(t1minTable);
DataStream<Row> t5minStream = tableEnv.toChangelogStream(t5minTable);
DataStream<Row> joinedStream = t1minStream.keyBy(new
TupleKeySelector("key", "id")).intervalJoin(t5minStream.keyBy(new
TupleKeySelector("key",
"id"))).inEventTime().between(Time.milliseconds(-1000L),
Time.milliseconds(1000L)).process(new ProcessJoinFunction<Row, Row, Row>() {
@Override
public void processElement(Row left, Row right,
ProcessJoinFunction<Row, Row, Row>.Context ctx, Collector<Row> collector)
throws Exception {
collector.collect(Row.join(left, right));
}
});
