--------------------------------------
Summary: AvroIO.write without specifying a schema
Key: BEAM-2993
URL: https://issues.apache.org/jira/browse/BEAM-2993
Project: Beam
Issue Type: Improvement
Components: sdk-java-extensions
Reporter: Etienne Chauchot
Assignee: Reuven Lax
Similarly to https://issues.apache.org/jira/browse/BEAM-2677, we should be able
to write to avro files using {{AvroIO}} without specifying a schema at build
time. Consider the following use case: a user has a
{{PCollection<GenericRecord>}} but the schema is only known while running the
pipeline. {{AvroIO.writeGenericRecords}} needs the schema, but the schema is
already available in {{GenericRecord}}. We should be able to call
{{AvroIO.writeGenericRecords()} with no schema.
