Description

Schema:

.withSchema(new Schema()
 .field("ip", Types.STRING())
 .field("ts", Types.STRING())
 .field("procTime", Types.SQL_TIMESTAMP).proctime()
 .field("environment", schemaEnvironment)
 .field("advs", ObjectArrayTypeInfo.getInfoFor(new Array[Row](0).getClass, 
  Types.ROW(Array("count","sid", "eventid","params"), 
  Array[TypeInformation[_]](Types.STRING(),Types.STRING(), 
  Types.STRING(),Types.ROW(Array("adid","adtype","ecpm"),Array[TypeInformation[_]] (Types.STRING(),Types.STRING(),Types.STRING()))))))
)

when execute this sql:

val sql =
      """
        |SELECT
        |ip,
        |ts,
        |params.ad,
        |params.adtype,
        |eventid,
        |procTime
        |FROM aggs_test
        |CROSS JOIN UNNEST(advs) AS t (`count`,sid, eventid,params)
        |""".stripMargin

I got a warning，and the console keeps brushing this warning,no normal printout

09:38:38,694 WARN  org.apache.flink.metrics.MetricGroup                          - The operator name correlate: table(explode($cor0.advs)), select: ip, ts, procTime, advs, sid, eventid, params exceeded the 80 characters length limit and was truncated.

But after I change it to this way, although I occasionally brush this Warn, it can be output normally。I change the 'params' type from Types.ROW to Types.STRING。

 .field("advs", ObjectArrayTypeInfo.getInfoFor(new Array[Row](0).getClass, Types.ROW(Array("count", "sid", "eventid", "params"),
          Array[TypeInformation[_]](Types.STRING(), Types.STRING(), Types.STRING(), Types.STRING()))))
