Fokko Driesprong resolved AVRO-2696. ------------------------------------ Fix Version/s: 1.10.0 Resolution: Fixed > 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 -- This message was sent by Atlassian Jira (v8.3.4#803005)
