             Summary: In JAXBCoder, use a pair of ThreadLocals to cache Marshaller/Unmarshaller
                 Key: BEAM-560
                 URL: https://issues.apache.org/jira/browse/BEAM-560
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-core
            Reporter: Thomas Groh
            Assignee: Davor Bonaci
            Priority: Minor


Marshallers and Unmarshallers are created per-element. Instead, they can be created per-thread and stored within a ThreadLocal which creates a new instance on calls to initialValue(), which allows them to be reused for all elements encoded or decoded by the coder.
