----------------------------------

             Summary: Avro IDL does not allow creation of avro.java.string subtype
                 Key: AVRO-3217
                 URL: https://issues.apache.org/jira/browse/AVRO-3217
             Project: Apache Avro
          Issue Type: Bug
          Components: java, tools
    Affects Versions: 1.10.2
         Environment: Java 8, Windows, macOS, Confluent Platform 5.5.1
            Reporter: Timothy Dimo


 

When using a Java application that has class files generated from an avsc file via the Avro Maven plugin along with the 
{noformat}
<stringType>String</stringType>{noformat}
switch set, serialization of records of the type string such as

 
{code:java}
{"name":"eventType","type":"string"}{code}
will fail. Changing the type to include an "avro.java.string" detail such as

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