> Key: FLINK-36320
> URL: https://issues.apache.org/jira/browse/FLINK-36320
> Project: Flink
> Issue Type: Improvement
> Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
> Reporter: haiqingchen
> Priority: Minor

> Hi I'm using protobuf format to read from kafka and there's a message type
> Test in the proto which is also a nested field in another message type
> TestObject
> {code:java}
> message Test {
> int64 startTime,
> int32 id
> }
> message TestObject {
> repeated Test tests = 3
> }{code}
> Here's how I define the ddl.
> {code:java}
> create table test_pb (
> Test Array<Row<startTime bigint, id int>>
> ) with (
> "connector"="kafka",
> 'format' = 'protobuf',
> 'protobuf.message-class-name'= 'xxxx.TestObject'
> ......
> )
> {code}
> I would like to use startTime field in the nested Test object as event time
> column and define watermark for it , but as it is a nested field in an Array,
> I can't simply use it. I would like to flatten the TestObject column but it
> doesn't work for DDL.
