Obviously this is not the case. since symbol "S7" is not present in schema1
and also it has no default value defined,

Hi,
I see that that java Avro compatibility check doesn't work as per
specification for enum schema evolution. I have a the following schema

Hi All,
Here is my situation, I have a SpecificRecord for a Schema S and I want to
convert it into a GenericRecord of a compatible Schema T (It is an older
version of S). I have seen many such examples but all strategies point to
serializing the SpecificRecord to either bytes or JSON and

Hi,
There are two implementations to czech schema evolution,
1. org.apache.avro.SchemaValidator (and it's implementations)
2. org.apache.avro.SchemaCompatibility
The SchemaCompatibility provides more information about incompatibilities.

Which is the right class to use to check compatibility?
I'm using Avro 1.9.2 and I'm trying to check the compatibility for the

Why can't the union resolution return a null if it cannot find an
appropriate or a branch of the same type. I
