[jira] [Created] (AVRO-3000) Avoid unnecessary schema compatibility checks

Joel Turkel created AVRO-3000:
---------------------------------

             Summary: Avoid unnecessary schema compatibility checks
                 Key: AVRO-3000
                 URL: https://issues.apache.org/jira/browse/AVRO-3000
             Project: Apache Avro
          Issue Type: Improvement
          Components: ruby
    Affects Versions: 1.10.0
            Reporter: Joel Turkel
            Assignee: Joel Turkel


Profiling Ruby Avro decoding of our event processing pipeline shows Avro is spending a fair amount of time validating that the reader and writer schemas are compatible. These checks are unnecessary for the fairly common case of the reader and writer schemas being the same. Eliminating these unnecessary checks when the reader and writer schemas are the same improves the throughput of our decoding benchmarks by 1.3X.

Github PR coming shortly.
