Hello, does anyone have a

DateTime

class that works well in Flink POJOs for efficient serde? I was using

java.time.LocalDateTime

but I see that Flink doesn't serde it efficiently, as per the log messages below:

2023-03-14 13:00:02 INFO  TypeExtractor - Class class java.time.LocalDateTime cannot be used as a POJO type because not all fields are valid POJO fields, and must be processed as GenericType. Please read the Flink documentation on "Data Types & Serialization" for details of the effect on performance.
2023-03-14 13:00:02 INFO  TypeExtractor - class java.time.LocalDateTime does not contain a getter for field date
2023-03-14 13:00:02 INFO  TypeExtractor - class java.time.LocalDateTime does not contain a getter for field date
2023-03-14 13:00:02 INFO  TypeExtractor - class java.time.LocalDateTime does not contain a setter for field date
2023-03-14 13:00:02 INFO  TypeExtractor - class java.time.LocalDateTime does not contain a setter for field date

I usually use Instant

Same as Jeremy here. For example, https://github.com/immerok/recipes/blob/main/kafka-json-to-pojo/src/main/java/com/immerok/cookbook/events/Event.java

Which version of Flink? I have not observed this issue in Flink 1.14 upwards which is in production for more than an year now

@Anshum Verma Flink 1.15.2
