Gwen Shapira commented on KAFKA-3174: ------------------------------------- As anecdotal evidence, 100% of the customers I worked with in the last 6 month have been on Java 1.8 (including everything from tiny startups to huge financial institutions). Looks like companies simply jumped from Java 6 to Java 8 directly. So I wouldn't be too concerned about a regression in Java 1.7. > Re-evaluate the CRC32 class performance. > ---------------------------------------- > > Key: KAFKA-3174 > URL: https://issues.apache.org/jira/browse/KAFKA-3174 > Project: Kafka > Issue Type: Improvement > Affects Versions: 0.9.0.0 > Reporter: Jiangjie Qin > Assignee: Jiangjie Qin > Fix For: 0.9.0.1 > > > We used org.apache.kafka.common.utils.CRC32 in clients because it has better > performance than java.util.zip.CRC32 in Java 1.6. > In a recent test I ran it looks in Java 1.8 the CRC32 class is 2x as fast as > the Crc32 class we are using now. We may want to re-evaluate the performance > of Crc32 class and see it makes sense to simply use java CRC32 instead. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
