各位大神求帮忙看一下。 Flink 版本：1.10.0 Planner：blink
我在使用Flink SQL的时候遇到了一个问题，能否帮忙看一下，我尝试在寻找了解决方法，但是没有起作用。 比如我发现类似的问题 https://www.mail-archive.com/[email protected]/msg03916.html 中描述的问题，根据这个mail中的解决方法我设置了timezone，但是问题没有被解决。 Flink Table Env配置 *StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();* * env.setStreamTimeCharacteristic(TimeCharacteristic.EventTime);* * env.setParallelism(1);* *EnvironmentSettings envSetting = EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build(); * *StreamTableEnvironment tableEnv = StreamTableEnvironment.create(env, envSetting);* *tableEnv.getConfig().setLocalTimeZone(ZoneId.of("Asia/Shanghai")); * 我这个job应用中定义了两个table，分别为source table “sqlDdlAnaTable” *String sqlDdlAnaTable = "CREATE TABLE ana_Source(type INT, datatime BIGINT, list ARRAY <ROW(id STRING, v FLOAT, q INTEGER)>, ts AS TO_TIMESTAMP(FROM_UNIXTIME(datatime)), WATERMARK FOR ts AS ts - INTERVAL '5' SECOND)" +* * " WITH (" +* * "'connector.type' = 'pravega'," +* * "'connector.version' = '1'," +* * "'connector.connection-config.controller-uri'= 'tcp://192.168.188.130:9090 <http://192.168.188.130:9090>'," +* * "'connector.connection-config.default-scope' = 'Demo'," +* * "'connector.reader.stream-info.0.stream' = 'test'," +* * "'format.type' = 'json'," +* * "'format.fail-on-missing-field' = 'false', " +* * "'update-mode' = 'append')";* 和sink table " sqlDdlSinkTable ". * String sqlDdlSinkTable = "CREATE TABLE tb_sink" +* * "(id STRING, " +* * "wStart TIMESTAMP(3) , " +* * "v FLOAT)" +* * " WITH (" +* * "'connector.type' = 'pravega'," +* * "'connector.version' = '1'," +* * "'connector.connection-config.controller-uri'= 'tcp://192.168.188.130:9090 <http://192.168.188.130:9090>'," +* * "'connector.connection-config.default-scope' = 'Demo'," +* * "'connector.writer.stream' = 'result'," +* * "'connector.writer.routingkey-field-name' = 'id'," +* * "'connector.writer.mode' = 'atleast_once'," +* * "'format.type' = 'json'," +* * "'update-mode' = 'append')";* 在数据处理逻辑比较简单，计算10s tumble window的vaule的平均。 我一开始直接打印结果能够明确看到10s中输出一次计算结果，watermark也正常移动。 *String sqlAna = "SELECT ts, id, v " +* * "FROM tb_JsonRecord " +* * "WHERE q=1 AND type=1";* * Table tableAnaRecord = tableEnv.sqlQuery(sqlAna);* * tableEnv.registerTable("tb_AnaRecord", tableAnaRecord);* *tableEnv.toAppendStream(tableAnaRecord, Row.class).print()* 但是我尝试将结果insert到sink table中发现，就没有任何结果被写入。 *String sqlAnaAvg = "INSERT INTO tb_sink(id, wStart, v) " +* * "SELECT id, " +* * "TUMBLE_START(ts, INTERVAL '10' SECOND) as wStart, " +* * "AVG(v) FROM tb_AnaRecord " +* * "GROUP BY TUMBLE(ts, INTERVAL '10' SECOND), id"; * * tableEnv.sqlUpdate(sqlAnaAvg);* 提前感谢！ BR//Chao
