---------------------------------------------------------
I resolved my issues using "avro-tools.jar compile -bigDecimal".
With this flag avro-tools generates my classes with java.math.BigDecimal
instead of ByteBuffer. And I have no exception when values are not null nor
null. All my tests are OK.
BigInteger are still converted as ByteBuffer.

I resolved my issues using "avro-tools.jar compile -bigDecimal". I'm not fully
sure because a lot of time has passed since.
With this flag avro-tools generates my classes with java.math.BigDecimal
instead of ByteBuffer. And I have no exception when values are not null nor
null. All my tests are OK.
BigInteger are still converted as ByteBuffer.

> I have classCassException with a bigDecimal.
>
> Context :
> I am doing an ETL with postgres >> KafkaConnect >> KafkaStream
> I get schemas with mvn schema-registry:download
> I generate pojo with : mvn clean avro:schema
> Then I launch my app to stream a table source to a table target
> see schema here : [^table.avsc]
>
> I have fixed passing on the 1.10.1 version and it works. But When i take
> 1.10.2 I have the bug :
