-----------------------------------
    Labels: pull-request-available stale-major  (was: pull-request-available)

I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help the community manage its development. I see this issues has been marked as Major but is unassigned and neither itself nor its Sub-Tasks have been updated for 60 days. I have gone ahead and added a "stale-major" to the issue". If this ticket is a Major, please either assign yourself or give an update. Afterwards, please remove the label or in 7 days the issue will be deprioritized.

> Flink currently generates Avro schemas as records with the top-level name {{"record"}}
> Unfortunately, there is some inconsistency between Avro implementations in different languages that may prevent this record from being read, notably Python, which generates the error:
> *avro.schema.SchemaParseException: record is a reserved type name*
> (See the comment on FLINK-18096 for the full stack trace).
> The Java SDK accepts this name, and there's an [ongoing discussion|https://lists.apache.org/thread/0wmgyx6z69gy07lvj9ndko75752b8cn2] about what the expected behaviour should be.  This should be clarified and fixed in Avro, of course.
> Regardless of the resolution, the best practice (which is used almost everywhere else in the Flink codebase) is to explicitly specify a top-level namespace for an Avro record.   We should use a default like: {{{}org.apache.flink.avro.generated{}}}.
