How do I handle @UDT annotation from Java driver 3.x in 4.x version?

I need to migrate from datastax 3.x to 4.5 .

Binaries are incompatible with such gap and UDT annotations from 3.5 needs some refactoring i think for 4.5 ds version.

Is the @UDT annotation dropped in 4.x series?

how to handle the same in 4.5.?

If possible please provide a reference example where UDT is mapped with a java pojo

java driver

Java driver 4.1.0 introduced a new object mapper in the 4.x series (JAVA-2078). Details are documented in the Java driver Mapper docs.

You can have a look at the discussion and example in the driver docs here. There are also code samples available at DataStax Examples. Cheers!

Really helpful answer.

Thanks !!

Any suggestions or example (which I could not find the github) for being able to define custom type other than java basic type and then use it inside cassandra code.
