Mark Wagner created HIVE-16408: ---------------------------------- Summary: SchemaToTypeInfo in AvroSerde makes many calls to synchronized functions Key: HIVE-16408 URL: https://issues.apache.org/jira/browse/HIVE-16408 Project: Hive Issue Type: Bug Components: Serializers/Deserializers Reporter: Mark Wagner
The generateTypeInfo method uses schema.getProp and schema.getJsonProp to retrieve metadata from the Avro schema. Both of those methods result in synchronization on the schema. generateTypeInfo is being called for every nullable field in every record, which makes it a significant bottleneck in multi-threaded use. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
