Description

 

When using a Java application that has class files generated from an avsc file via the Avro Maven plugin along with the 

<stringType>String</stringType>

switch set, serialization of records of the type string such as

 

{"name":"eventType","type":"string"}

will fail. Changing the type to include an "avro.java.string" detail such as

 

"name": "eventType",
            "type": {
              "avro.java.string": "String",
              "type": "string"
            }

will succeed.

 

It is not possible to create this "avro.java.string": "String" detail via the Avro IDL language. The schema creator must first create the avsc file then manually update all of the "type":"string" fields.
