Timothy Dimo created AVRO-3217:
----------------------------------
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.
