----------------------------------------

             Summary: I wish to remove optimization from GenericDatumReader.getResolver
                 Key: AVRO-1809
                 URL: https://issues.apache.org/jira/browse/AVRO-1809
             Project: Avro
          Issue Type: Wish
          Components: java
            Reporter: Konstantin Usachev
            Priority: Minor


There is an optimization at org.apache.avro.generic.GenericDatumReader.getResolver, when we cache creator thread and it's first returned value. At first, It looks redundant, because it saves three calls to Map.get, which is unmeasurable, especially after Schema's hashcode calculation optimization, made by the same author [~cutting], it's not obvious and adds additional complexity. Also caching of current thread whould be a source of bugs in case of different green threads libraries integration (which, actually, occurred during integration with Quasar).
