> Improve Avro Double and Float Encode Performance

> 
> Key: AVRO-2696
> URL: https://issues.apache.org/jira/browse/AVRO-2696
> Project: Apache Avro
> Issue Type: Improvement
> Reporter: David Mollitor
> Assignee: David Mollitor
> Priority: Minor
> Fix For: 1.10.0
> 
> 
> I was looking at how Avro encodes Doubles and Floats and comparing it to Java's.
> So, I checked it out and found that the Java version for Floats is faster than Avro \
> using the Avro perf tests: {code}
> # Avro Impl
> FloatTest.encode  thrpt    3  273709210.133  ± 49629107.871  ops/s
> FloatTest.encode  thrpt    3  271515727.631  ± 57405372.266  ops/s
> # Java Impl
> FloatTest.encode  thrpt    3  278234438.923  ± 34633982.243  ops/s
> FloatTest.encode  thrpt    3  284801936.136  ± 52273884.157  ops/s
> {code}
> Interestingly, I wasn't able to reproduce this gain with Doubles.  Avro's version \
> was faster.  However, we can remove the bitwise mask (Java doesn't bother to do \
> it). https://github.com/openjdk/jdk/blob/6bab0f539fba8fb441697846347597b4a0ade428/src/java.base/share/classes/java/io/Bits.java#L105
