Konstantin Usachev created AVRO-1809:
----------------------------------------
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).
