Sandish Kumar HN commented on SPARK-40659: ------------------------------------------ [~rangadi] is the reason being confluent schema registry not open-sourced? I see that Apache Flink uses a confluent schema registry [https://github.com/apache/flink/blob/master/flink-formats/flink-avro-confluent-registry/pom.xml#L39] > Schema evolution for protobuf (and Avro too?) > --------------------------------------------- > > Key: SPARK-40659 > URL: https://issues.apache.org/jira/browse/SPARK-40659 > Project: Spark > Issue Type: Improvement > Components: Protobuf, Structured Streaming > Affects Versions: 3.3.0 > Reporter: Raghu Angadi > Priority: Major > > Protobuf & Avro should support schema evolution in streaming. We need to > throw a specific error message when we detect newer version of the the schema > in schema registry. > A couple of options for detecting version change at runtime: > * How do we detect newer version from schema registry? It is contacted only > during planning currently. > * We could detect version id in coming messages. > ** What if the id in the incoming message is newer than what our > schema-registry reports after the restart? > *** This indicates delayed syncs between customers schema-registry servers > (should be rare). We can keep erroring out until it is fixed. > *** Make sure we log the schema id used during planning. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
