----------------------------------
Summary: idl2schemata: same types in different namespaces =>
overwritten files
Key: AVRO-2728
URL: https://issues.apache.org/jira/browse/AVRO-2728
Project: Apache Avro
Issue Type: Bug
Components: tools
Affects Versions: 1.9.1
Reporter: Jarek Rosiek
For the following AVDL:
{code:java}
@namespace("ns1")
protocol Proto {
record Foo {
ns2.Foo foo;
}
@namespace("ns2")
record Foo {
int x;
}
}
{code}
the tool will generate just a single file named {{Foo.avsc}} with the schema of
the last record Foo.
Suggested solution:
Add an option to the {{idl2schemata}} command named, for example, {{-fqnames}}
that will make the tool generate files named using full qualified type names.
For example, for the protocol shown above the files would be named:
{code:java}
ns1.Foo.avsc
ns2.Foo.avsc{code}
Impact:
My company wanted to use Avro IDL as a specification format for the schemas
(more readable, ability to import other files). We need to push the schemas to
kafka Schema Registry. We could use {{idl2schemata}} to generate schemas in
JSON format but we risk pushing wrong schema whenever different teams working
on schemas from different namespaces create a type with the same base name.
