             Summary: Performance issue in AvroUtils.checkTypeName
                 Key: BEAM-12210
                 URL: https://issues.apache.org/jira/browse/BEAM-12210
             Project: Beam
          Issue Type: Task
          Components: io-java-avro, sdk-java-core
    Affects Versions: 2.28.0
            Reporter: Daniel Kulp
            Assignee: Daniel Kulp


AvroUtils.checkTypeName (which is called a LOT) is always creating a 
StringBuilder and doing a bunch of appends and toString's even if the condition 
is true.   It's not using a proper format  string and varargs for the 
parameters.  This results in a lot of extra objects being created when using 
Avro.
