----------------------------------
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.
